More points vs. Fewer points

[Greenham]

I'm not sure this question belongs here, but none of the other categories' seemed right either.

I have been planning a 4 day trip broken into Day 1,2,3,4 routes. After getting the routes the way I wanted them, Compared with TomTom/Open I reduced my routes from 5 Way points and 40-50 shaping points, down to 5 waypoints and 20-30 shaping points. The routes stayed the same with all 3 planners.

Is there a down side to doing this?

These routes will be uploaded to my Garmin Zumo XT and I will have MRA running w/ AA on my motorcycle.

@Greenham my experiance with XT tells me not to save on shaping points
The XT tends to have a way of its own. Better safe than sorry

@Greenham Hi there,

I always try to reduce the shaping points to the only necessary number of them. In mist oaf the cases it perfectly fits, but yes: Sometimes the XT or - in my case - the XT2 has minimal differences which are not really relevant for me.
My approach was, that I tested several things and approaches and find the best solution for me.
Important ist, that you do your tests and setups for exact your workflow. It can makes a difference, if you use the Drive-APP, Thread-APP or for example like me a SD-card to transfer the GPX-files onto your Garmin device.

Greetings

As I like to travel on the narrow Country Lanes as much as possible, I always put at least 1 waypoint on every road I plan travel on.

@Lynchy67 Je suis également confronté au comportement du XT2. Le problème est que quand un recalcul de route est effectué par le GPS, il supprime les shaping point de l'itinéraire initialement prévu et ne garde que les via points (obligatoires).
Si vous désirez passer un via point en modifiant un peu votre route ou si ce point n'est pas correctement placé dans votre itinéraire, le XT2 vous fera obligatoirement passer par ce point et il n'est pas toujours possible de dire au GPS de le passer manuellement. C'est là que les ennuis commencent.
