what does these stats mean?

Exactly how he writes Niko, so it is.
4-4-2 is unpredictable disposition, and I never know what to expect.
3n-4-1-2 now it does not work. Use 3n-1-4-2 or 4-5v-1 and work perfectly.
The last 2/3 of the season happens to me, I do not win your opponents by 40-60% weaker and that just sucks. 7-8% is no difference in quality teams.

I would use 4-1-2-1-2 Narrow Diamond against 4-4-2 Classic.
Once upon a time, 4-4-2 Classic beats the Narrow Diamond. But the opposite is true now.
