One of the core concepts in Jim Wendler’s program/s is to keep 1 in the tank, work at 90% not 100%. If you do strain 100%, then the 4th week you’re taking a deload week (roughly 50% of the weight, just tickling the muscles really). That’s because any 100% strain on a 1-2 rep will require about couple weeks of recovery.
Also, if you’re eating in surplus, and you managed easily your +set, then increase by a maximum of 5kg every 3/4 weeks squats/deadlifts, and no more than 2.5kg shoulder/chest. (given you’re past newbie gains, which you should be if you’re using this type of setup and concepts).
I like to use www.blackironbeast.com, like I posted earlier in another post, if you like Jim wendler’s setups it’s a quite nice free website (and it remembers your setup/reps/weights everytime you go back on the website).
