Why is MRA making a totally different route when waypoints are added (with openstreet map)?
Seemingly that is due to a randomize function in the automatic creation of scenic routes. A curvy route between 2 points can be different from a curvy route between three points, even when the middle point is on the original 2-point route. That does not sound completely illogical to me.
WP should be added to the route that was created with OPM as well as it is done with TT map.
Remember that routes are calculated by the map-providers, not by MRA. Each map provider does things differently. That is nothing new.

Sorry Con, but it is totally illogical. With this tool, one expects MRA maintains the route. The route is already calculated, why not put the new added points on the route "as is", that would be logical. There is no use of a "new calculation" because the parameters for calculating the route didn't change.

Sorry Lex, but MRA maintains nothing except a web planner tool. Calculations are done by mapproviders. Each adding of a waypoint triggers recalculations. Rest assured: I really don't know whether OSM has randomize functions in it's curvy routes calculations or not. But what happens here makes me think so. And it would have a purpose. No one wants the exact same route each time they create a roundtour from home.
But I agree completely that the difference shown by in the first post are pretty dramatic.
I am just an enthusiastic MRA user, and hope you will be one too!

@Con-Hennekens I didn't wrote, that MRA calculate the route, only that the route has been calculated, and therefore the gray line is somewhere stored. The only thing MRA has to do with the expand, is follow that line and put shapingpoints on that line

@Lex.Kloet.RX, the grey line is not stored, it gets calculated each time. Only waypoints are stored.

The calculated route must be stored in some way. If I calculate a route with OSM, I can navigate "route as track" in the original shape, regardless of how HERE calculates the route.

@Martin-Wilcke, Yes, a low resolution track is stored with each route for use with the "route as track" feature. This has been added pretty recent. It is however NOT used in any planning features though, and that is only logical because we are talking routes and not tracks. The web planner is a route planner not a track planner.

Ahh, thanks, got it. But the "low resolution" track looks pretty detailed

Ahh, thanks, got it. But the "low resolution" track looks pretty detailedDon´t rely on it looking pretty detailed. It isn´t.
For 1.5 seasons now, I´m using route as track navigation for all of my tours. Yet, there are deviations that I still cannot explain. Yeah, to rise the challenge, I´m also doing it in offline mode, too. I got into some situations, yet always managed to by any obstacles. The point is: use more points! Shaping points, Via points, just use them.
There have been good hints like comparing the route to the other map suppliers, too. Or saving a .gpx from TT, one from OSM, one from HERE or an existing tracklog and adding them to blend in and see what´s really going on. The more effort one puts into planning (and using given tools), the more satisfying the final route will be...
Anyway, have a great (rest of) the season!
By the way: if anybody is interested in my routes and tracklogs, just send me a friendship request. The routes are pretty well described, why many tracklogs are not. My apologies, lack of time b/c I prefer riding. But I guess that I have some interesting stuff available I did through the last years. Covering mostly Italy, France, northern Spain, some Austria, Germany and Czech, too.

I also use "route as track" navigation a lot. The main reason is the lack of a "curviness" option with HERE, so I use TT or OSM for planning instead.
My routes have 3-5 VIAs and a handful of SPs, and I let the routing engine do its job.
As all these roads are typically routable with HERE as well, there's hardly any difference when it comes to navigating the route (as track). And if so, it's easily manageable - the same applies to some erratic behaviour that occurs from time to time (very rarely).It may depend on the areas you're riding, but in my case, this works very well.
Have a great riding season as well!
