I honestly doubt that is even a decent indicator of faction balance. I (or any of the players you took stats from) could severely inflate those numbers (think 20+ streaks) by intentionally queuing during off-hours. Streaks in the top 10 are generally just an indicator of which players are noob-stomping the hardest.
Furthermore, look at the current UKF 1v1 top 10. UKF has a total streak of 99......prodi currently makes up 44/99 of that. A single fluke loss by him, and that value youre using gets lowered to 54 (around 45%). It's similar for most other factions, though not as severe.
Another word that I just thought to add, but if youre going to be doing these kinds of statistics, youre either going to need the randomness and sample sizes to ensure the results are relevant, or enough context to properly interpret and explain them (think tournament/streamed matches where the wins and losses can be analyzed and the players are known). I just don't think that measuring top 10 streaks has either of those.
I think you missed the part where I said barometer ie it's an indicator maybe not perfect and yes could be influenced heavily if someone chose to do so, but I do think it does highlight the Ost regardless as being weaker than the rest.
One question for you (being a top 10 player), when the tournaments go to a rubber match where the faction is chosen by the vp count holder, does axis get picked the majority of times now?
Btw, I didn't post to pick holes in the flaws of the methodology. I wanted to see if this study aligned with the sentiment i am reading that says Ost is not any good and Jackson is OP.
