<I've been working on some sanitary drains recently, and I'm pretty familiar with calculating the drop across whatever distances I'm running. However what I'm curious about is why is there such big discrepancies between what everyone says is "standard"?>

Michael - It's all a relation between flow / pipe size / & velocity, google for sewer sizing chart - look at: Environmental Engineers' Handbook
by Béla G. Lipták - 1999 - Technology
a couple pages into the text you will find a self explanatory chart, the only other thing of interest is an author's statement of 3-7fps velocities , I seem to remember 2fps as OK p.s. I found the identical chart in my old Fluor design guide - date: 1958 - not much changes in this industry - huh
