No matter how you put it, falling out of an airplane and recovering to be able to lift like you are is a huge accomplishment. Unless the plane was on the ground and you tripped getting in, just kidding. Anyways, the cues are a matter of the coach giving them. Some say to sit back and some say to sit down. I am more of a sitting down type. I think a lot of the multiply guys use the cue to sit back a lot because of the gear. I would just keep the timing of the break at the hip and the knee a little closer.
What you could try now is to either maintain your weight and increase your numbers or to maintain your numbers and decrease your lift. Either way you are progressing in my opinion but it depends on your goals. If you want to squat 500 then I would maintain bodyweight and try to increase your numbers. A little extra fat padding never hurts to help with your lifts. Anyways, good looking squat.
