Welcome to the forum! DL 40lb over squat looks like a healthy ratio for a novice, even if increases have slowed down - and since you are above three plates and a bit into the novice program already, DL once a week + powerclean sound like a good idea. Just gotta be patient and eventually transition into an advanced novice routine lift by lift after squeezing every bit out of LP.Deadlifting has not been keeping up with the squat and I can't figure out if I'm doing to much or too little. Tried adding a bit more reign didn't seem to work, so I'm going to switch to DL once a week, with power cleans and chin ups.
Good luck!
