Forgive me for not going through all 58 pages, but I have a question regarding how different events do their scoring system. I gather few places hold actual 'competitions' (as opposed to a more open-play setting) but it's what works for our events.
In the 2 years-or-so of events we've held, we've narrowed it down to 2 distinct formulas, then a subset of 3 slightly-different formulas from there. So four-ish... kind of. I've only recently started to question it's balance and accuracy though, so I figured I'd ask and see how others handle it.
A) The original, and probably best one, was based on each song's highest possible score (pulled from scorehero generally), the global highest possible score (gght at 3.9mil, last I saw), and a small addition to compensate for band-difficulty. The end result is an individual song multiplier you multiply into the band's score. Perfect in every way, except that it heavily relies on someone posting the 100% all expert full band score for every single song. A year and a half ago, there weren't nearly as many songs so it was fine. Now, not easy to do.
B) The current one we use is based on the percentage each player gets, the band difficulty, and the player difficulty levels. All the needed information is right there, so no scorehero research across hundreds of songs. The downside is that it's explicitly performance based; it doesn't take into account the score itself, and more importantly, the overdrive multiplier/streaks/points. I'm not happy about that, but in the end, I think it balances itself out. A band that gets an average 98% on a song probably hit all the overdrives very well, would have scored high either way.
C/D) Both a modification of the second one there. Still doesn't account for overdrive, but C does add the option of individual instrument difficulties, and D changes the order in which things get mathed out (a different of 1600 and 6400 is a big scalar difference!) Both of these really may be a little more/less accurate that B, but they're both incredibly messy when it comes to the actual math.
Again, I know I'm probably in the minority here with my setup, but this IS what works for us, and that's how people like it. We're just doing some fine-tuning here and there. If anyone wants to know the actual formula itself, I'd be happy to post them.
