I've done the first autotune ride; I tried to get all the cells filled. This is just a start.
Tomorrow I'll do some more riding and maybe even reading.
I was surprised to note that it did not give the 'over 125' error and ask to scale or cap. I am just running the basic AT, though.
I expect the Pro AT won't be long coming.
Here's what it looked like
I noticed a whole lot of the various error messages popping up during the run; NBR0,NBF+ and ET+ and others. They changed a lot and didn't linger. I don't know what frequency of error is "normal".
