Hello,
Trying to find the exact ratio here would be a waste of time imo. I don't know it and never bothered trying to find it since the game is too dynamic to create an exact range with the same ratio against everyone.
First of all, you have to make assumptions on how often you get 4bet or 5bet from what your opponent raises/3bets.
Next, you have to assume there is no more postflop play, which is not the case.
Last but not least, being balanced won't be MaxEV since the whole idea of being aggressive and 3betting is to put pressure on opponents to get them out of their comfort zone and force them to make big mistakes.
Against people that play OK vs 3bets you can just get some idea of their 4betting range and work out a 3bet/5bet range from there, same with 4bet/call it off. Also to consider, why would you want to go to war against someone that plays well against you? It makes no sense, your target should be the fish and regulars with obvious leaks, not the solid players.
Regards,
Manu.
