Gopro cameras - Data analysis and video overlays

I’ve come across some very cool software to try out with my GoPro CAMs, saw it in a Facebook advert. I’m new to the data analysis thing so just wanted to see if anybody had used it before?

I like the idea of doing the video overlays, but I’m mostly interested in the data analysis to try and make the most of my track time and master the tracks.

Software is from Race Technology:

Has anybody used this or something similar before?

Do you have any tips for the data analysis, I’ve got the basic idea but are there any top tips of things to look for?
