So some heavy stuff went down in world of tanks forums yesterday, someone reverse engineered the game, and posted the info he found. Heres part of it dealing with camo values.
Most of the people in the forum got banned for reposting the info etc.
World of tanks staff are denying any of this is real, but from what ive seen in game and from other posts in vehicle comparison forum, id say its pretty real, and matches up with other findings with visibility.
Check out the different in quality of russian camo moving and unmoving.
Quick reference of camo values.
These values are modified by your average camo skill and net. I guess something happens when the resulting value exceeds 1.0.
<0.1 basically no camo ability, camo skill/net are pure waste of time/money
0.1 bad
0.2 eh
0.3 fair
0.4 good
0.5+ stealth ninja
first value is when moving (speed don't matter) / second value is sitting still
