Now have a fourth route option - decisions decisions (on the day probably)
I must admit, compared to the BBR it's both nice but also frustrating having more time to plan as I'm getting annoyed with myself as to which one I should go for. Another spooky thing is when you've planned a route then hit the 'invert' button it often makes quite a bit of time difference going the other way round, either better or worse.
I've also noticed that even though Garmin Basecamp is meant to plan a 'fastest' route if you manually tweak the route to take you slightly off course i.e. onto another major road it can gain you several minutes which means overall you can gain quite a bit of time
But as I've already mentioned, during rallies you never seem able to keep to your planned ETA's at each bonus location. Well, you can for the first few hours if you're lucky but then it always goes to pot and I always end up dropping some locations to get back on track.
