I was doing preflop stuff with my excels when I think I noticed a mistake on one equation, luckily I haven't really used it so far.

I think I corrected it but can someone check this for me? I'm trying to calc the EV of 4betting given different assumptions of R.

Fold equity pre * (3b size + RFI size + blinds) + (1-fold equity pre) * (equity when called * potsize when 4b gets called)

This now results in 4bettor having an EV = potsize with 100% equity and 100% R, sooo it should be correct imo.
