I still stand that the OD could be lowered to 9.5 probably, what kind of noteblock are you going to get with OD9.5 that you're gonna fix with OD10?
Good question. Let's find out.
Let's say an OD is good enough for a certain bpm if you can always hit an early 300 after missing a jump, like 180bpm OD7.
This map's bpm mostly fluctuates between 240~250bpm and has a long 270bpm section full of singletaps, so let's take those three bpms.
OD9 is no good:
240bpm - almost half of the hit window of early 300s (~ 25ms) is taken by the previous circle's hit window. The early hit window is effectively restricted to 15ms. As people usually hit jumps earlier when they miss one, this is pretty bad.
250bpm - same as above, but now you have 10ms.
270bpm - you can't hit the note perfectly on time, but you can hit it like 2ms late.
OD9.5 doesn't improve the situation by much:
240bpm - you can hit early 300s (you must be at least ~2ms late actually), but not early 100s, barely acceptable.
250bpm - you only have 15ms of early 300s. Not acceptable.
270bpm - you can actually hit the note on time now, but you can't hit it earlier than ~5ms.
OD10, which is the best we can do, and it is barely acceptable:
240bpm - no complaints here, OD10 is decent for 240bpm jumps.
250bpm - can't hit early 100s, OD10 is barely acceptable here.
270bpm - half of the early 300s hit window is gone. But the 270bpm singletaps in the map aren't jumpy at all, they could play like a stream, for which OD10 is more than enough.
Nomod ODs for streams of this bpm are simply hopeless, with OD9.5 being relatively worse than OD8 on 200bpm.
OD8 on 200bpm streams means that if you miss a note in a stream, you'll have to start streaming at least 45ms late to not notelock. On OD8, that means you'll be streaming 100s about ~13ms later than what you'd need to get 300.
Likewise, missing a note in a OD9.5 250bpm stream means that you'll end up streaming at least 45ms late. The difference is that, to get 300, you should've have started streaming ~23ms earlier, and you're closer to getting 50 than to getting 300. So, to compensate, you'll have to overstream faster/for more time, at a higher bpm to boot.
OD10 is still worse than OD8 on 200bpm, but you'll be streaming 40ms late, and you have only a ~18ms disadvantage to recover.
Even OD7 DT would've been better, in fact it would've been great, its hitwindow for 50s in 87ms, compared to the 100ms of OD10.
TL;DR: nomod OD's hit windows for 50s fucking suck and notelock everything, OD10 is a must on this map because of that. Play DT for saner hit window scaling.
