Thx for those additional replies. Sounds like about where I have it set is good. Interesting comments about the other options of tracking your data. I will have to look into that.

On the gps... yea, I dunno... I had a hill that I looked down and the Garmin hit one number for the grade. When I went to look for it in my graph later in TrainingCenter it did not register.

I know the hill had to be steeper than the graph... in my story I'm going with the head unit grade.
