there was only a 10 lbs difference between 99 and 01 ASC. I already gave a plausible reason why he had up to 3 lbs less fat. This leaves only 7 lbs to explain, which I propose is how much less water he carried. When you consider how much flatter his quads and pecs looked, this figure is not farfetched.
Your math sucks, plain and simple. Accepting your argument would imply agreeing that Ronnie was at 4% bodyfat at the 1999 Olympia, when the reality is that no one knows exactly what his percentages of bodyfat was at either contests.
You also argued that he carried more lean mass, "maybe only one or two pounds", so that would be 11 or 12 pounds to explain. Now let's get the low figure of 1 lbs and do the math. Let's also accept your idiotic argument that Ronnie was at 4% bodyfat at the 1999 Olympia. Ok. So:
11 lbs - 2.87 lbs = 8.13 lbs
So, you have 8.13 lbs of bodyweight that can only be justified via water loss - if it is accepted that he gained even a single pound of lean muscle tissue from the 1999 Olympia to the 2001 ASC.
I hate to break it to you, but a healthy, fully hydrated Human Being does not have 8.13 lbs of water in the whole body to lose, let alone a contest-ready bodybuilder like Ronnie at the 1999 Olympia. Losing that much of water in his physique would be impossible, as he would die.
And take into consideration that I'm being very generous in accepting your ridiculous argument that Ronnie was at 4% bodyfat at the 1999 Olympia. Most likely, he carried the same percentage of bodyfat at both contests, with the difference in conditioning being water. So:
11 lbs - 0.30 lbs = 10.70 lbs. That's close to 11 lbs that you would have to explain via water loss: impossible.
Now, I'm
still being generous, because while you have showed a quote of Ronnie being 247 lbs, I have a FLEX stating that he was 244 lbs - and NarcissisticDeity posted it. Going by this figure and accepting that Ronnie was at 4% bodyfat at the 1999 Olympia and 3% bodyfat at the 2001 ASC, then:
14 lbs - 2.96 lbs = 11.04 lbs. That's over 11 lbs of weight loss to be explained via water loss, which is utterly impossible.
And, if we accept the most usual figure that Ronnie was 3% bodyfat at both contests, with the difference in conditioning being water loss, then:
14 lbs - 0.39 lbs = 13.61 lbs. That's a thick fat 13 plus pounds for you to explain via water loss, sport.
In conclusion, Part I: at the very least, Ronnie has 8.13 lbs of unnacounted weight to explain via dehydration, and perhaps as much as 13.61 lbs - assuming the most likely scenario that he was at the same bodyfat percentage on both contests.
And guess what? In either case, it is impossible! Again, even a healthy person does not have over 8 lbs of water weight to lose before dehydration sets in, let alone a contest-ready bodybuilder who's already dehydrated.
In conclusion, Part II: Ronnie carried less less muscular mass at the 2001 ASC than he did at the 1999 Olympia. Saying otherwise is illogical both from the point of view of physiology as well as mathematics.
