Hey there, guys!
Beatmap Link
I have a rather massive issue with the rhythm choice in a certain section of this map, I'll explain it using timestamps from the Insane

Here is a screen of the sheet of the measure starting at the head of 01:24:585 (2) - http://puu.sh/oj3z7/b71826923a.jpg
The measure of the complete piece is simple 4/4, and as you can see, the head of 01:26:441 (5) - is the next downbeat, and is noted as a 1/16-note like all the other notes around it, but is played by the cellist with a massive slowdown. Pishi interpreted that as if it were 1/8, like 01:24:585 (2) -, and thus thought that 01:26:778 (1,2,3,4) - was on-beat. The thing is, it isn't on-beat, causing the need to insert a note somwhere to get back to on-beat again, as the next downbeat is at the head of 01:28:009 (6) -. His sliders make it seem like 01:27:789 (5) - would be the downbeat though, and then suddenly another note gets inserted, making it seem like Bach was composing mad jazz-stuff with 9/8-measures. And that repeats for the next three measures, always being off by 1/2 but making it seem like it's onbeat and having to insert an additional note somewhere.

It might be hard to get your head around how the rhythm emphasis is 'supposed to be' once you see the map, so I slightly modified the diff to show how that would go, look for yourself: http://puu.sh/ooujk/7aa6319218.osu
It isn't really noticable that pishi's sliders are offbeat at first because the cellist simply doesn't emphasize any note stronger than another, meaning that whatever emphasis you put on it seems right, but it is very clear that there is a certain way the composer intended this to be, being 4/4-measures like the rest of the song and not 9/8 or other jazzy stuff, and maybe it is more easy to see how messed up the rhythms currently are if you look at the lower diffs of the mapset too. In the Insane, at least 01:30:883 (4) should be rather easy to detect that it's actually offbeat.

(btw here's the full sheet with 01:24:585 being highlighted for better orientation)

I had discussed this with pishi when it was just bubbled, and he understood that he was pretty off but didn't want to change it bc he wouldn't have liked that, but I feel pretty strongly about this song (having shot 50 stars at the set lol), so yeah

Looking forward to hear your opinions!

Mapping is about interpreting the song and your interpretation is what's closest to the notesheet.
pishi's interpetation is what's probably better for standard gameplay in that sense since he just followed "what's a bit more emphasised" which would probably be what's easier to interpret for players lol.

Also try to cut your argument down to a few words that get to the core of things quickly here's how i understood your point:

You wrote much text to say that there's a notesheet which doesn't emphasise the notes that pishi mapped so that a few of his sliders seem offbeat according to it. You think that this is an issue and should be discussed so you made this thread.

wohoo

tbh, its fine for me.

at first it felt a bit wonky, but it felt pretty natural after listening to it a couple of times.
anyway, at least he is very consistent with how he did the rhythm so i see no problems here.

the music is pretty ambiguous in the first place so.. ya it can be interpreted both ways.

Just to clarify in response to Oko, I'm not just basing my argument on "this is how the sheets are, everything else is bad" - Directly after these four measures (can't provide timestamps bc phone), the NCing is off by 2/1 according to the sheets for a long time, but even to me that is totally fine because the cellist very clearly emphasizes it like that. What I wanted to show by providong the modified diff is that in the adressed section, nothing specific is emphasized at all by the cellist and (at least for me) both ways of emphasizing seem to fit equally at first. But my main point is that pishi's way leads to the rhythm appearing like it's 9/8, and I don't believe that 9/8 is easier for players to grasp than 4/4 with slowdowns similar to the whole rest of the song, bc as mentioned they would expect the next downbeat at (5) but them suddenly it is delayed to (6), and that it doesn't fit the rest of the song/map since it is 4/4 everywhere else.

@Kibbleru about it being consistent: I can't provide timestamps bc I'm on my phone, but have you looked at this section in the Hard? iirc it is mapped there like a mix of 9/8 and 5/4-measures, the combos aren't equally long there I think, so I wouldn't call that 'consistent', and it sure isn't consistent with the rest of the map being 4/4 : /

Mmm pishifat way works better in my opinion, both ways are fine, at this kind of cases I guess is better to let the mapper keep his way. At least in osu standard 01:25:406 (1,2,3,4,5) - work better as a group, since this 01:26:441 (5) - sounds more as part as the previous section rather than the start of new one and 01:26:778 (1) - feels as the start of the new one, same apply to 01:28:009 (6,1) - and the next ones.

The way you propose seems correct from the sheet perspective, but doesn't feels that nicely from a gameplay perspective.
