I also like the wholistic approach for comparing bikes with similar intentions. Although…head angle and seat angle are tough to measure properly. Chainstays, fork length and headtube (along with wheelbase) are easy to measure / harder to fake. Calculating reach from horizontal front center is one way to see how believable the posted numbers actually are. I’ve also found that correcting reach to a set headtube length is useful.
FC/RC ratio is something that I think should be used more often in reviews. Playing with adjustable stays on my bike is huge for balance and fatigue.
