@Mzokk Thanks for the confirmation. I'm a simple man who doesn't want to get bogged down in the nuances of possible exceptions to what happens most of the time. In my short period of testing and use of 1.2 GPX routes, my firm conclusion is not to make any modifications that would trigger a route recalculation. Off-route recalculation for re-entry is OK, because the base route itself is not modified. My first instinct will still be to reenter a route under my own control, but the option for the Zumo to do that for you is clearly there.
Everybody has their own approach to route planning/creation/execution. At a high level, my separation of duties is that all route modifications happen at the MRA Routeplanner level. If I want to make any Shaping/Via point changes, I go back to Routeplanner, perform the updates, and then re-copy the route back to the Zumo. In other words, Routeplanner is the repository for managing my routes. I have my own folder system for keeping everything sorted out. I view the Zumo as the execution layer. Similar in concept to the old IT Client/Server model. It's just one way of doing things, but it's a simple separation of duties and it works for me.
As a side note, in being active on this forum, it seems like many members view routes as a "suggestion" that should be flexible to change through repeated skipping of waypoints. That seems to me where a lot of people get tripped up. I guess different views on things are what makes the world go around.
