Someone said that I should post this in here instead of in the Feature Requests forum. This is about star rating more than performance points, but I hope it still applies.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------I think that the circle size and approach rate extremes should be weighted more in the Catch the Beat star difficulty rating.
I currently have almost 1500 SS ranks in Catch the Beat. Most of those scores are from maps in the 1.8 star and below difficulty range. Around 98% of all of the SS ranks that I have obtained took me anywhere from one to three tries. A few took anywhere from four to fifteen. I was fine with the amount of tries even if it took ten or so. Everything was going great until I ran into
Pixel Studio - Gravity [ZOMGWTF]. I've tried that map 226 times and I still haven't even gotten half way through with the perfect mod on. If you don't know what this map is then you are in for a treat because it has a CS of 7, an AR of 10, an OD of 10, and a HP of 9. With Catch the Beat, the map requires fantastic precision and memory.
Is my lack of ability to get a SS rank on this map because I'm simply just not good enough? Yes, but that doesn't take away from the fact that this map should be, in no way, only 1.49 stars in Catch the Beat. Now, I don't claim to know the intricacies of the formula for the Catch the Beat star difficulty rating, but I think something needs to be changed. Weighting approach rate and especially circle size extremes more for the star rating should be able to bump this map way up to at least closer to where it should be.
I do recognize that changing a formula that applies to 40,000 maps to address a problem in only one map would cause more problems than it would fix, but this formula change wouldn't just effect this map since it would beneficial for all small circle size maps. It is consistent that the small circle size maps take me much longer to SS than maps with a normal circle size. In fact, all of the maps that took me more than around six tries were the under-weighted high-CS maps. Through this, I genuinely believe that this change will improve the level of polish in osu!, if only slightly.
Thank you for reading! Have a good day.
