Hi everyone!

I wanted to make some field math on crew exp with all the modificator active during a Top of the tree special.

Played on my T-57 Heavy Tank i've got for a win:

694 base exp

1041 due to premium account

2603 for crew member

5206 for selected crewmember with "accelerate crew training" active

given that is active the x1.5 for a battle and x2 for a win, i wonder why my math wont give the right numbers:

The last count is correct, cause 5206 is 2603x2, as explained in the wiki (the least exp member earn x2 exp).

For the other, i thought that i have to write: 1041 x 1.5 x 2 = 3123, that is experience given in the battle report, x 3.

But, extracting the multiplier from effective exp: 2603/1041 = 2.5.

So, how i get the x2.5 multiplier from x1.5 and x2? what am i missing here?
