Interesting- different light to be sure, still, I believe that most judges would rather tell you to find a way to lose more water that to tell you that you just weren’t lean enough. Seriously, I think they want to break it to you gentler.
However, I have looked at these several times now & my very first reaction was that in 2014 the physique looks more mature. Obviously, the 212 weight class- so similar weight. But, having read the forum, mirrored the training log, followed Meadows, etc., I think the objective as I understand it is to obtain a full, dense, rounder muscle head and, it appears that you have done just that over time. Maybe in '07 you weren't as "big" and needed to get more shredded than the competition? I mean, not a huge fan of P. Heath, but, he talks in detail about being around 250 onstage vs. Greene, others who are 30 pounds heavier. So, you go for "roundness", symmetry, density, and maturity of the muscle. I have been to one Olympia & tons of amateur shows- that's my disclaimer- but, the vascularity in '07 reminds me of amateur shows where lack of size is compensated for by simply getting shredded as heck. Can't even account for intangibles though, like the toll that dieting/cutting took on you Mark doing so many shows in a row in 2014- or, maybe even "overtraining" as in so many sessions per week as you have mentioned here recently?
