It depends on your goal i guess.
I could careless how much I lift. Im in the gym purely for bodybuilding purposes and to break my targeted muscle down as much as possible. If i didnt sleep well last night and didnt get many calories this morning, i go into the gym and use as much weight as gives me resistance for 12 good reps. if thats 185lbs then so be it, the muscle got completely broken down. if i slept like a baby and crushed the food today and go into the gym, i may use 250lbs to get 12 reps, but the end goal was the same...the muscle got completely worked. Do you see what im saying?
My guage of progress is my physique so i dont care about numbers. if you are purely in the gym to lift more weight each week then go ahead and keep track, but poundages dont mean much when it comes to bodybuilding.
i just think every rep, every set, of every workout is way overkill. You're numbers are gonna vary daily based on diet, sleep, mood, etc. You'll end up fucking yourself up because you lifted a little less today than yesterday. It's not a big deal. Maybe every few weeks record your numbers, thats a better indication of progress.
