TruSail: training analytics

It is the bit that happens in Excel (or wherever) that interests me. You've got a few thousand numbers representing heel angle... but how do you take those and actually interpret them to say "you didn't hike hard enough" or "you're getting better at keeping it flat".

What about all the times the app records a heel angle of ten degrees, but it was because you were mid-tack? You need to excuse those ones!

You can’t look at heel angle in isolation, out of context. So a single number answer won’t work. It needs to be viewed over time, in relation with heading, speed and ideally wind strength.

I think the main issue is to have a readily understandable real-time display which gives you data you can take in quickly from the corner of your eye, given the number of other variables you need to be looking at.
I've experimented with iRegatta and RaceQs on both watch and mast-mounted mobile phone and found it too hard to be able to switch focus between the screen and telltales, boats, wind, waves etc. Post race analysis with video is useful (when augmented with the data) but real time feedback would be much more useful and accelerate the improvement process.
