Now in a game in EFC mode we all know it's way easier to force a 50/50 then secure a 100% win because people do try to play in a more intelligent way than the fast and instinct based tournament mode
So this is a trick to slowly increase your ELO against higher level opponents. Against low level opponents if you play properly you will win most of the time anyway
Anybody with a higher/much higher or even equal ELO score to you, the trick is like this:
A) If you have a good matchup, play the game properly, you are likely to win.
B) If you have a bad matchup, force a 50/50
C) During the 50/50, instead of relying on your instinct, flip a coin to choose how you will play. Because of how the ELO point system works if you win 50% of your matches this way, you will always have an increasing score
This could be an interesting way to get a high score if you are a nervous player and don't want to rely on instincts too much
