Hello everyone, this is my first time posting here, I have a bit of a question.

 

For a while now, my in game statistics and my xvm statistics don't line up. for example my xvm winrate is 51,60, while my in game winrate is 51,36, with my xvm, my stats also don't line up, there is a diffrence of 22 wn8. While I don't mind, I am still curious as to why this happened.

XVM = Random battles only

In-game Service record =  Random + Company battles
