I think there's a distinction between mapping 1000s of "favourite" tours (bad) and identifying the handful of good through route-sections that no-one's bothered to signpost yet (good, I think). Finding routes in cities, there are often subtleties that don't get tagged, and would be very difficult for a router to pick up by algorithm, however much objective data you throw at it (eg - priority at junctions, phase length at traffic lights, viable speed, 85%ile car speed etc). Whereas if you throw a few "this route works quite well" sections at an algorithm, it's got a chance. I'd say we should have an agreed way of tagging "recommended" route-sections, so that we have choice whether they go on maps, and whether they get used by algorithms. Whereas I'm not so convinced by grading individual route sections (for urban cycling): it's just another piece of micro-data for the algorithm, when what is needed is some meta-data.
