So in reference to: http://www.cybercircuit.net/2009/08/ion-drum-rocker-challenge-rob-prod1gyx.html
A discussion came up on twitter over what method will be used to score. Here’s my opinion on it… First, I took a look at the rundown of the known information about the way they want to score:
- Percentage of notes hit
- Level of difficulty of song (as determined by highest score recorded on Scorehero.com)
- Longest run of notes hit
Yea.. it made no sense to me either… but then I found out this tidbit:
- Since all qualifiers will be within a full band during normal events, we’re going to take your % and weight it to how hard song is
Ahh ha! Okay, so I asked:
So MyScore would be My% of the Top on SH? Or just higher score songs = harder than lower score (visions doesnt break top10?)
They asked for an opinion after that, so I commented:
Would prefer @cybercircuit scores using My% of Top Score w/NS tiebreaker
and linked to this post to explain why this would be the most fair given the circumstances… Heres why:
If a ranking has to be formed based on % and Note Streak alone, there needs to be some way to mathematically evaluate the differences between two performances. Score exists for a reason, and is generally what all competitions are based on. This makes sense. So how would I do the math? Take the % that the player receives, and calculate that percentage of the top score from scorehero. Then use Note streak as a tiebreaker. This works great if you assume that everyone will FC every song (as Note Streak would differentiate who got the squeezes under the activations, because they aren’t counted in %).
Whats the disadvantage here? Well if you assume that all the top players will be able to 90% or higher each of the songs, the only ones worth playing are Panic Attack, Painkiller, Teen Age Riot, Ramblin’ Man, Battery, Bodhisattva, Let There Be Rock, Lazy Eye (everything else would give you a score of less than 300k even if you FC the song). Also, this scoring completely ignores OD usage (the scores on SH are top scores with perfect paths, and often also have the under-OD squeezes also) – but that is really the price that has to be paid to take scores from BQP.
But, if we want to even out the competition a bit, there could be a wonky way of giving extra points based on Note Streak. Still calculate the %, but then, for each note in the the players NS, add 25 points to that score. How would this work out in practice? Lets look at some examples (note that the difficulty of each song is increasing with each player):
Player A plays “Eye of the Tiger” and scores a 100% with a 1331NS
they score 158375+33275 = 191650
Player B plays “Shooting Star” and scores a 98% with a 50NS
they score 209279 + 1250 = 210529
Player C plays “Carry On Wayward Son” and scores a 98% with a 640NS
they score 210675 + 16000 = 226675
Player D plays “Let There Be Rock” and scores a 99% with a 2500NS
they score 378037 + 62500 = 440537
Player E plays “E-Pro” and scores 100% with a 1449NS
they score 181775 + 72450 = 254225
Player F plays “Spoonman” and scores 99% with a 500NS
they score 192233 + 12500 = 204733
Player G plays “Panic Attack” and scores 95% with a 200NS
they score 416741 + 5000 = 421741
What do we see here? Player D wins. Why? Because while player E may have FC-ed a song within the same approximate difficulty range, “e-pro” has no-where near as many notes to hit. Similarly, player G went for broke and played a rediculous song, but because he couldn’t hold a combo (despite doing very well) – he comes up short.
This system rewards players for playing at/slightly above their skill level, on complex songs that have large volumes of notes. A player who can 98-100% any of the aforementioned top scoring songs will still probably win, but a player who can 96-97 a fairly challenging song within his skill level will still have a chance if an “elite” player doesn’t show up…
Just my thoughts… take em for what you will..
