Overall winrate of the last week

[Gentercz]

Is your feature request related to a problem? Please describe. There is no „winrate of the past week“ thing, i could really use that for my analysis.

Describe the solution you'd like I just need a winrate in % next to the „ x battles/ 7days“ thing

Describe alternatives you've considered

Additional context
