I 100% agree that it is not a replacement - augmentation is probably a good term. Just thinking of ways to sell this - one being bringing a sense of competition to skiing without the time or monetary commitment of going to a tournament.
I don’t think you’ll sell it to the early morning slalom crews by saying “pay x dollars for us to determine your average for you.” You’ll sell it by saying “pay x dollars to compete against your buddies AND skiers across the country without changing your normal routine.”
Then, ideally, once they get hooked, they will want to meet up with their new friends and prove themselves at a tournament.
Obviously I understand this all takes money (and probably much more than I can even imagine it would), but I also don’t think it’s worth the time and effort if it’s just going to be an excel sheet posted to a website like the current rankings lists. Coming from someone in finance - there is only so long you can keep someone’s attention on a spreadsheet. If it’s just logging in, staring at some numbers, then logging out, I wouldn’t pay to join that. I would pay (much more than $20/yr) for an interactive, social platform where I could virtually compete with my buddies any given Saturday morning across 5 different states, watch people skiing around the country (similar to my ability level, the top dogs, or see watch some nice rookie OTFs), all with some BOS type commentary layered in (asking for tips, recommendations, etc). The social aspects need to be there, you need people to want to log in, browse, and waste time on it. We need all the great social aspects of skiing that @jcamp mentioned earlier... just the 21st century version.
