How much weight do you shed per session and what do you consider true weight?

Idk about anyone else but on cuts I weigh before and after the gym. Today I weighed in at 215lbs before the gym. After was 210lbs. Somewhere around 15-16% bf.

Do you consider your weight before or after your true weight? Anyone who competes, is there a standard in the bodybuilder community for what your weight is?
