Yesterday my PP suddenly somehow rocketed to 2k and today it drop again to 1,3k

Bummer.

2341pp, rank 58110
My PP and my rank don't follow. :/ For some reason my rank went from 38k down to 58k last night, even as my PP should make my rank the former. I was previously at rank 56k with 1711 pp.

Perfect bonus is surprisingly high... a bit lower?
Many hards give less points that the respective sets Insane as referred by some players
EDIT:
I expected a #560 Insane and a #168 Hard "did" gave some pp. Instead I losed 1 pp.

I'm not sure what you are trying to say but if you are wondering why you got pp for passing the hard map and not the insane you probably haven't read anything available regarding pp otherwise you would know exactly why a rank over 500 would give less than a rank under 500. You do however seem to have a point - hard difficulties can give just as much, if not more than an insane. If it's not the hardest difficulty it shouldn't give pp after a player has accumulated a certain amount of pp (tweaked for approved maps). A players pp from easy maps should be limited to say 500 in total, normals 1000 in total, insane 2500 in total and approved/higher tier 3000 in total. Of course this would be a terrible system and giving pp based on a maps actual difficulty would be 200% more accurate.

Right now it's like someone has picked a bunch of random maps and then took a random difficulty inside said maps and put them as the most rewarding save for a few high reward maps.

Currently this: Beck - Timebomb (IcePagoda) [Normal]
Is worth more than freedom dive on four dimensions.

take the list with a pinch of salt, didnt winshley rank 1 that with a hd fl SS and only gain 20 pp at 5.2k? even though the weighting is lower on 4d i bet if he rank 1'd it he'd be gaining 80+ ATLEAST

i gained 40 for a rank 1 i set the other day at 5.7k pp and it was like 300th overall on that list

I was pointing out how this map was worth nothing on pp, while most hards give more and are much easier. It's not because it's old or it has received a few plays, so I guess there's some problem in the algorhythm

This give seriously more points than it should, for example

AH, I didn't strangely get points for passing Insane and Hard of Bokutomo's OP(map linked in my previous post), instead I saw my pp decaying by 1 point ( I losed 1 point )

Did you play something a year ago? Because another map might have reached that magic 1 year number, which makes it worth no pp.

this chocoliti guy seems to have gained at least 200pp from when cookiezi played for him, and none of the scores are even FC as far as i can see. imagin if someone beat him on freedom dive another, or got FC on 4D, im sure they would gain more than just a bit of pp

edit: unless you are serea, then you dont get any

A thing I like about pp is that there is actually some hope in getting higher ranks without grinding on easy insanes for score. I'm #88 for taiko in Canada, #7108 world wide! I've been enjoying this system.

that's only the case in taiko. in standard, grinding is a possibility.

yep, he got 0pp

There are map that are worth MANY pp that are 4 years old. That map was worth no pp while being LESS than 3 month old. and still played like high-pp worthy maps.

So the algorhythm need some adjustment.

hes saying that you might have gotten a score 1 year ago, so that stopped giving pp.
