I do know what I am talking about. Unless the MP3 file is 'trick photagraphy', then you will obviously see that Chuck only moves the weight 10 inches or so. That is clearly visible. There are guys Chuck's weight that are squatting 75 to 80 percent of what he squats and they go three to four times the distance he does all the way to the floor with NO SUPPORT GEAR!
Have you ever seen an elite Olympic Athlete train? I think not. They train 6 to 7 days a week, TWICE a day on most days. Also many Super Heavy Olympic Athletes are squatting 900 lbs for a single (or more) going way below parallel. This is without a SUIT, or KNEE WRAPS (or even a BELT in many cases) or a MONOLIFT. I, like many people, am tired of records falling due to all the 'EQUIPMENT' and a with such a very small range of motion (like the 1000 lb. squat that moved 10 inches). If he would have gone to parallel or even broke the plane, he would have been buried under the weight and probably would be dead or at least a crumpled mess! This no great feat 1-dawg.
Once again like I said before, Paul anderson moved 6 times the weight the same distance over forty years ago with no SUPPORT GEAR. That is probably the greatest strength feat of all time. Real squatters move the bar more than 10 inches and they break the plane and go 'slightly' below parallel. If Chucks' squat to you is 'a good' squat (and a great '10 inch' effort above parallel it was), then you are certainly entitled to your opinion and so am I. And to answer your question, yes I have been to a few meets in Daytona when I used to live in Orlando. I was also being sarcastic when I referred to the 'Smith Machine' as a 'monolift like device'.
Bracing your feet on the inside of the Monolift does indeed provide extra leverage. It is Physics 101 (have you ever had Physics?). It has to do with the concept of the stabilzation of your 'Base of Support'. Suppose I tried to squat while standing in an ice rink. Why would I do only be able to squat 1/2 as much (1/2 as much is a 'rudimentray' example) as I would at the gym under a rubberized mat? It has to do with my 'Base of Support'. You see most of my effort has to be 'channeled' towards focusing on balancing my feet on the slippery ice of the ice rink, rather than being channelled into the effort of the squat motion itself. My feet are going to want to slip to the inside, outside, back or front because the ice is slippery. I now have less 'leverage'. Now if my base of support was to be stabilized (ex. I squatted at the gym on a rubberized mat) then I could squat more weight because the rubberized mat underneath my feet is much more stable then the ice. I have better 'leverage' due to the fact the more of my effort can be channelled into the lift itself and not into the function of 'stabilizing' my 'base of support' (my feet). If one was to 'brace' their feet on insides of the monolift, then more effort will be channeled into the lift itself because however hard their feet are pressing into to Monolift, the Monolift is pressing back into the feet with a force that is equal (directly proportional - another topic of Physics 101). This again stablizes the base of support providing even more leverage. 'Base of Support' is also one of the factor why a person can squat more on a Smith Machine, than squatting freely out of the rack. It is also why a person can leg press more than they can Smith Machine squat. It is because the 'Base of Support' is stablized more in the Smith Machine than it is in squatting freely. And the 'Base of Support' is stabilzed even more in the leg press than it is in the Smith Machine.
You have been a ref for a long time and you don't even know the most basic of Physics principles? I you don't understand how one can be ref in the sport if they don't even understand basic Physics and have never even taken Physics 101. Go and sign up for Physics 101 at your local Community College then you will have much better understanding of what you are watching at a powerlifting meet.
