There is a bug in the current implementation of the manageable x3 xp multiplier. It adds too little xp. Compare the following two situations:

- For the first victory of the day, the multiplier adds +300% xp (example: base xp 950, x3 button adds +2850xp ).
- For any battle after the first victory, the multiplier adds +200% xp (example: base xp 1637, x3 button adds +3274xp)

This last +200% is against the promise for which I bought premium time. The movie Wargaming published clearly gave examples in which it always is a +300% bonus:

- Example 1 (0:52): daily double xp: 1414xp. Base xp: 717 Bonus adds +2121xp.
- Example 2 (0:57): base xp: 980. Bonus adds +2940xp
- Example 3 (0:58): base xp: 800. Bonus adds +2400xp
- Example 4 (0:59) base xp: 1800. Bonus adds +5400xp
- Example 5 (1:00) base xp: 820. Bonus adds +2460xp
- Example 6 (1:01) base xp: 560. Bonus adds +1680xp

I collected some additional evidence to prove that the current implementation is not working consistently:

Battle 1 - 1st win in a tank: bonus adds +3489 xp, with a base xp of 1163 xp --> 300%

Battle 2 - 2nd win in a tank: bonus adds +3132 xp, with a base xp of 1566 xp --> 200%
