I believe the different routing apps and sites may still plot different routes, even working from the same OSM data.
In a way that makes sense. IF
the tags in OSM are reliable (big if, obviously) then it would be perfectly possible for very different cycle route apps to be correct for their target audiences:
"Hardcore Mountain tough guys routing"
"Lycra Olympic wannabe on 22mm tyres and carbon thing"
"Tourist with 4 panniers, tent, kitchen sink"
Those three cyclists would probably want very different routes.
I don't know if the granularity, or even just plain accuracy, of OSM is good enough to allow market segmentation like that, but hopefully one day it will.
