Is there one?  I'm trying to plot the Grand Union canal and after 78 waypoints I cannot add any more.

Correction, 89.

In theory it's 500. In practice it's likely to be lower, though, because the list of waypoints will exceed the length of a URL that a browser or webserver can cope with – so 89 doesn’t sound too outlandish.

I've been playing with the new 'delete unneccessary waypoints' feature, it looks good to me, no errant course changes in the routes I've tested it on.  In so doing I found an error in the OSM data which I think I've corrected:

Would you mind casting your expert eye over it?  The changeset comment should explain what/why I've changed.  There are so many park boundaries that intesect there I'm nervous of having moved the wrong node and redrawn the boundary of a park by a few feet.

If I got it right it'll be interesting to see if the waypoint that was uneccessary in presence of the error still is.

Yep - looks like it's fixed!
