Let's add some more information
EDIT: 1vs1 stats
A bit of SPC flow chart. the SPC flow chart is a method to monitor a process in order to improve it - here, each faction meta in the current meta. How does it work: it takes the average (from each day faction victory ratio - from the google excel doc) and show the limit of the process/balance. I took the data from 15 to 25 sept but I cut the graph in two side as a patch has been deployed on 23 sept, so a modification in the game meta/process. To analyze the data after 23.9, I need more daily data, at least for a complete week.
What the meta/process is: Top200 players + game balance. If a patch goes out (like the 23.9) we reinitialize the flow chart.
If we look below we can see that OKW faction is design for a victory ratio that goes from 59% to 82% until 23 of september
So in fact, during that period the OKW meta is build to not let the faction going below 59% victory per day.
USF faction, 49% to 71%, so the faction meta has been design to be 10% less effective than OKW faction.
To know how it goes after this last patch, I need the same data from 23 to today and a bit more days to improve the calculation of limits.
If someone wants the flow chart for Sov and Ostheer, I can add them, but since they're between OKW and USF ratios, it's not going to show much more.
