I think it works well for me and I actually worked backwards and got my PBH from my saddle height. I have a hard time measuring PBH due to obesity and my wife and I measured it at 83cm (5'11"). I can straddle an 84cm S.O. bike and still bend my knees a bit so I know 83cm isn't accurate. From my SH of 75cm, I assume my PBH is 86'ish cm. With slightly thicker soled shoes, I would go with a S.H. of 76 cm. Luckily, the 86'ish estimate gives me clear size recommendations on the Rivs I would want to own. 54 Hunq (53 is probably an option now), 55 Appaloosa and 52 Bombadil.
