Thanks for sharing your rationale, Tikk. Here is how I calculated my proposal:

Same step two as yours without step one. My friend (next door neighbor in Hamilton Hall) and I have been debating this for years. He's in your camp, wanting an equal distribution or at least a bell curve.
I dismiss his opinion because A) It annoys him and that's what friends are for B) He was a heavyweight who never had to deal with weight cutting, the sport within the sport.
On the other hand, I sucked a tremendous amount of weight (we're talking high school here. I wasn't even good enough to advance past district one sectionals) from football to wrestling.
Back then your three highest weights were 167,185, and heavyweight. Our heavyweight was Eric Seaman who was undefeated as a senior until he ran into Kurt Angle in the state semifinals.
Our 155 pounder had regional aspirations and no reason to bump to 167 with Chris Kwortnik roaming that jungle. The kid I beat out for 185 (barely but consistently) was built like a Greek god with no fat to cut to 167. Down I went. Twice.
My metabolism has been shot ever since. My growth plates shut shop on me and I grew only one inch taller afterward, topping out well short of my father, uncles, and male cousins on either side.
So yeah, considering I gain five pounds if I so much as glance sideways at a doughnut, I have an axe to grind when it comes to weight cutting. That is why I have set the weights to incentivize more trips to the weight room instead of the sauna. Starving sucks.
