Hi, since I do not have right to post in mathlab section I am posting it here: I got a database of currently 113896 active wot players and 1517 clans updated daily and after 30 days of collecting data I have already 1757386 records in it. The database is growing every day as visitors of it search new clans and new players. I could publish a table of avarage values per tank which could help with generating wn8 expected values. Let me know if anybody is interested looking into my data. Size
Hi all, Sorry if this is the wrong subsection, but I couldn't find anything better. I've been looking at the penetration values at different guns, and I've been wondering how WG finds these values. For example, I've seen values at 90 degree, 45 degrees, 15 degrees, etc. Which ones do they use? Thanks
Most of you have heard some players discuss the camouflage values of a tank and possibly they threw around some numbers 16.87%/12.65%/3.34%. If you have no clue what those numbers mean, this is the guide for you. If you have ever driven (or seen someone drive) your (their) AMX 13 90 on the Malinovka field while spotting tonnes of enemy tanks and not getting counter-spotted, without understanding why, this is the guide for you. I will in this guide explain what the camouflage values mean, how they affect your view range in game and how the spotting range is calculated. I will NOT discuss the effect of single-double-triple bushes in detail in this guide. There are several other guides on this subject. I will also NOT go into detail how to exploit the spotting system. This will not be the most advanced guide. This should be considered basic stuff for any player aiming to be blue or higher. All camouflage values in this guide are taken from the following document. I want to highlight that this document is not my creation. I am just linking to it. https://docs.google.com/spreadsheets/d/1w9YYhDuNWJKSdIPesGhS4YkZJodEqUSFoomumMWYynA/edit?pli=1#gid=355532698 Camouflage values In the simplest terms: The camouflage value of a tank is indicative of how stealthy the particular tank is. The greater the camouflage value is, the harder a given vehicle is to spot. Each tank in the game has three camouflage values: one for when it is stationary, moving and shooting. All scouts tanks (except the T-54 LT for some reason) have the same camouflage when stationary and moving (one of their only advantages over medium tanks). As an example let us look at some camouflage values: Bat Chat 25t camouflage values: 16.87%/12.65%/3.34% AMX 13 90 camouflage values: 17.67%/17.67%/4.21% AMX 50b camouflage values: 3.82%/1.94%/0.53% So without going into detail about what these numbers mean in practice we can see a few things from this simple comparison. The AMX 13 90 has the same camouflage value for moving and stationary confirming that it is a scout. The Bat Chat is almost the same as an AMX 13 90 when stationary and slightly worse when moving. The AMX 50b is not a well-camouflaged tank. Even when stationary and NOT shooting it has worse camouflage values than an AMX 13 90 blazing away. Protip: do not go camo-sniping in your 50b. Camouflage values in practice Now what does the 17.67% camouflage of the AMX 13 90 mean in practice? It is part of the (quite elaborate) calculation that is carried out when the game determines if two vehicles can spot each other. You can ignore the calculation and use a simplified calculation if you just want to understand in broad terms how the camouflage of your tank affects the spotting range of any enemy tanks trying to spot you. You can also look at the proper calculation in way more detail if you want to fully understand how different crew skills, consumables and equipment influence the spotting calculations. I will now go through both the simplified and advanced way of calculation the spotting range. I will assume you know basic math, but I will try to make everything as clear as possible for those who might feel a bit rusty on the old calculus. You can decide for yourself which of the two sections you want to read. Simplified calculation The simple way to calculate how a camouflage value affects the view range of the spotting tank is: spottingRange = ViewRange * (1 – camoValue) So if you are in an E100 (view range = 400 m) and you are trying to spot an AMX 13 90 moving across a field (AMX 13 90 moving camouflage = 17.67%) the formula looks like this: spottingRange = 400 m * (1 – 0.1767) = 329.32 m This shows you the practical result of a higher camouflage value. The higher the percentage the camouflage has, the equally higher percentage will be taken of the view range of the spotting tank. If we do the same calculation but with an ELC AMX (camouflage value of 21.89% when moving) we find that the spotting range of the E100 is now: spottingRange = 400 m * (1 – 0.2189) = 312.44 m So from this calculation we can see that the ELC AMX can move 17 m closer to an E100 compared to an AMX 13 90 without being spotted. Now you might be thinking: “But when will the AMX 13 90 or ELC spot the E100?”. This is easily calculated using the same formula. We know the view range of the AMX 13 90 and ELC AMX (400 m and 360 m respectively) and the camouflage value of a stationary E100 is 2.91%: spottingRange1390 = 400 m * (1 – 0.0291) = 388.36 m spottingRangeELC = 360 * (1 – 0.0291) = 349.52 m So the AMX 13 90 will have a “window” of 60 m to move around in where the AMX 13 90 will have the E100 spotted but the E100 will not spot the AMX 13 90. For the ELC this window is only 37 m because of the poor view range on the ELC. Now a word of warning: all of these calculations are SIMPLIFIED calculations. They ignore anything outside base values, so no crew skills, consumables or equipment is taken into account. This is especially important in regards to view range enhancing skills and equipment. If you want a slightly more precise calculation you can take any optical equipment into account. Coated optics adds 10% to the base view range and binoculars add 25% to the view range of a stationary vehicle. Advanced calculation The advanced calculation is using the following formula: spottingRange = effectiveViewRange – (effectiveViewRange – 50) * camoFactor That doesn’t look to bad, does it? You take the effective view range and subtract the effective view range minus 50 m (the proximity spotting range) and multiplied with the camo factor of your tank. Easy stuff, right? Sadly this is only the main formula. There are two supporting formulas to calculate the effectiveViewRange and camoFactor. Let us start with the camoFactor. The formula is as follows: camoFactor = baseCamo * (0.00375 * camoSkill + 0.5) * camoAtShot + camoPattern + camoNet + environmentCamo Now this may seem like a big mouthful with a lot of strange labels and coefficients, so I will try to break it down for you: The baseCamo is the camouflage value of the tank either moving or stationary, exactly as I explained in the start of this guide, and it is multiplied with the camoSkill (along with some coefficients) and camoAtShot. The camoSkill is the ‘effective’ camo skill of the crew members. This is a combination of the crew camo training, commander skill level, premium food consumable, improved ventilations equipment and the perk Brothers in Arms. The camoAtShot is the camouflage value for firing the gun. If you want to calculate for a tank that is not firing, this factor is neglected. After these three factors are multiplied, you add the following: camoPattern, the bonus for any camo patterns (value depends on vehicle type); camoNet, the bonus for active camo net (10% for mediums/lights, 5% for heavies and cancer, and 15% for TD’s); and finally environmentCamo, the bonus from any bushes the tank might be hiding behind (single, double or triple bushes). So now you know what goes into calculating the actual camouflage value of a tank, let us now take a look at the effectiveViewRange factor. Sadly I have not been able to find a formula like I did for camoFactor, so I can only list the different factors that influence the effective view range of a tank. Each tank has a base view range, similar to their base camouflage values. This base view range is then subject to different factors (again, similar to the base camouflage values). First off there is the equipment of coated optics and binocular telescopes that adds 10% and 25% respectively (although binoculars only active when stationary). Then there is the effective primary skill of the commander which is controlled by his own training, improved ventilations, Brothers in Arms and premium food. Lastly there are also the recon and situational awareness crew skills for the commander and radioman respectively. In total, if you mount/train everything that can possibly enhance the view range it is possible to increase the base view range by an amazing 44.5-ish%. This means that a tank with 400 m view range will have an effective view range of 577.90 m. Now I hear you ask: Why would I want to have a 558 m view range when the maximum view range is hard-capped at 445 m? If you limit your view range to 445 m you will not be able to spot anything at maximum spotting range – because the camo factor of all tanks will decrease your view range down below max spotting range. If you on the other hand have an effective view range of 500 m the camo factor of some tanks will not be able to force it under the maximum spotting range and you will indeed spot them as soon as they enter the maximum spotting range. I could now give you a practical example of both camoFactor and effectiveViewRange, but that would quickly become a mess and a waste of the time of everybody. Instead I highly recommend you go play with the camo-calculator on wotinfo.net (http://www.wotinfo.net/en/camo-calculator). Here you can type in your vehicle name together with an enemy vehicle to counter-spot your vehicle. You can then see how the camouflage values (and spotting ranges) changes depending on all the different factors mentioned above. It is a great tool to play with, and understand, how the camouflage works. I hope you learned something from this guide. I certainly did, which is always a nice plus.
