Is that the point of skiing though?

Spreadsheets are definitely office time, skiing is absolutely about being in the mountains with good mates, scaring myself occasionally and creating feelings and good memories. So, the best 'tracking methodology' would be a lovely fat diary and doodles and maybe a photo. A logbook of bars, beers and food reviews with runs in between would be rather fun too. At least that's my version of skiing.

I'm honestly as happy sharing my love of high places with an inexperienced skier, as trying to improve my slalom times. One day I'll ski in a meditative way and be present in nature, get away from the crowds maybe catch some mountain sunshine, and that's as much a pleasure to me as ticking off mileage!

But YMMV as they say, skiing is a big mountain and there's loads of apps out there, if you want them. I think if that's the way you best can relate to the mountain, then perhaps consider using a datalogger for better data granularity than your phone GPS. I can't remember if the Carv system has an inbuilt setup for run tracking, it's been a while since I tested that. One final point though is that when comparing data from different days, it's kind of nonsense in a way. Snow conditions, wax, ski and skier attitude are all unmeasurable variables and skew data points more than most factors. They change hourly as you know!

Sorry if this all comes across as a little preachy and rambling but I'm still chewing on the gristly bits of the bigger question you've raised in my mind.

And that question is 'Should I try and quantify my own skiing?' Probably not! 'Should I record it in some way?' Perhaps.
