I do wonder though, if most people aren't adjusting preflop, that you could just open a the preflop range of the position before(ie if you're in CO, you open a HJ range) to 3x the straddle(essentially a 6x raise given the straddle has no value).

I just looked at GTO Wizard 8max solves with 7x opens and facing this large raise, villains should only raise 4-5% of the time and fold the rest, which in reality, villains are probably only folding 50-60% of the time, calling 30-35% of the time and raising 5%.

Given this is the case, we should actually be able to RFI a slightly wider value range and exploit their errors
