No, it is not correct. This is THE biggest misunderstanding of 5/3/1
The training max increase has almost nothing to do with your actual max and how it changes. Just because your TM increases 5 pounds doesn't mean your real max will go up 5 pounds... Maybe more,maybe less
So many factors come in to play. Diet, genetics, training age, amount of assistance work and type, etc... The last thing on the list is increasing your TM 5 pounds having a 1:1 correlation with your real max
What if at the end of 4 months you bench 220x8 on your last week? Would that be an improvement? What if in cycle 6 you are benching 225x4?
The training max does not correlate 1:1
