I have recently started using HLT and am really struggling to work it out. I have tried reading the docs, but they seem to mostly be for older versions and for the life of me, I cannot work out the logic of the app :-/ I am sure if you wrote it, or have used it a lot, it all makes sense, but to me, I can barely find the same thing twice in a row because I cannot follow the logic of where it is. Anyway, let's assume I am being daft - so please can you help?!

As background, I do sprint racing, which means there is no traditional lap, which adds some complication. I am using a GoPro 5 for video only, so iPhone camera not in use. I did get that connected and controlled by HLT for my laps. I tried loading a track map, which partially worked, as it was detected and tried to make laps, but of course, start and stop is all wrong and now I have 23 partial laps instead of 7 sprint races. I recently did a sprint at Blyton Park in the UK, and seem to have data, lap lists and video (not all talking to each other!).
What I want to achieve:
1) Edit and/or create Sprint Track POI's from original track layout so it keeps the original POI's for corners etc, but I replace start and stop with Standing Start Go and Stop in different places instead.
2) Create new Sprint Track POI's where no existing track exists - preferably just on a map so I can place corners etc.
3) Fix my Blyton Park sprints so they combine to form one 'lap' instead of being split. I want to view them as a single lap each time, rather than it being randomly split when I hit the official lap Go point

4) Export these sprints with video and overlay so I can share via YT or wherever.
Please can someone help me, as I have read and re-read documentation till my heard hurts and still cannot work it out

Thank you,
Graeme
