I am definitely an anomaly when it comes to maxing charts. I realize they are guidelines, but I am way off.
For instance, I repped 225 15 times the other day, on a cut, after doing heavy sets.
The most I have EVER benched is 295.
Most max calculators put me quite a bit higher than 315, usually 330ish.
For my purposes this is better than the other way around, as I have a 225 reps test in the near future, but I am still curious about the answer to this riddle.
