Ok. This is helpful. I can see the Red reference vs. the lap I selected with the track in the upper left corner. Also, I noticed if I click on the track map I can get a red line and see the data at any point on the track. Thanks!

How can you compare 1 lap to another lap? For example, on my Traqmate I can see the speed against time -- same on Harry's. However, I can compare / overlay another lap and visually see the speed differences against time. This way I can see I am faster/slower in a particular corner, etc.
