My opinion only, there's only so much shit ya need to know Terry. Won't be long and some of this stuff will be giving us tyre pressures and have us pulling up because we dropped a pound. Basic info is fine, lots of info has people worry and takes the fun away.
I agree with the above, unless you are planning on racing I dont think knowing all the fine details is of any benefit. I have the standard simple control unit and I dont crave for any further info, I think the app can record some extra bits for you but I must admit, i connected the app to the bike when i first got it and then never looked at it again.
If you want to get a review of your ride then the Strava phone app is good for that.
