Thanks for the feedback, Coach. If I were to wait until I no longer feel the previous set, I wouldn't do the next set until sometime tomorrow, but point taken. I went from 5 to 7 minutes because I was really feeling the previous set with the shorter wait and I have no problem adding more time. It's not like anyone else is ever waiting to use the squat rack.
Any chance I'm overdoing my warmup sets or taking too big a jump between them? Yesterday I did 45 x 10, 135 x 5, 195 x 3, 235 x 2, 280 x 1, then work sets at 305.
