How about a mod that will auto-fail you if you are not able to score higher than your previous high-score.Absolutely love this idea! I currently do not play with any of the perfect mods ever, because my goal is usually a 90% acc and to get like 95% of the full combo.
The coding would just need to assume and give you the best possible score at the moment you are in the song.
current score + highest possible score obtainable in the remaining song = Best possible score
if Best possible score < Previous high-score = fail
spinners will be assumed 300 + spinner bonus of previous high-score (if that data is there, if not just regular 300)
Your Selective Perfect mod might be another way of this mod that I had in mind, but maybe you could mesh them together or something? I would love to see a mod that will help people gradually get better by setting the bar little bits higher and higher.
It is then completely useless to play perfect or the slightly kinder version. If I miss the 5th last hit circle I will most likely still get a really big PP boost from it and I'd probably be happy having it there for a while. Perfect now would completely remove that score because it has higher expectations that I have.
A mod that simply helps you reach a higher score without me having to do some averaging math to figure out if I can still beat my score with the circles left. This I do quite often midmap and does make me miss a few circles every once in a while.
EDIT: Just threw 22 stars at it, would litteraly play a mod that only allows better scores 90% of all my plays.
