Bringing this up for further explination from loctav's mod.
01:50:785 (1) - In this section here you need to decide on 1 SV to use. The pace of the song does not change at all so i'm not seeing why multiple SV changes are happening, just 1 will do. The way you have it going now is pretty unreadable until you've played it a few times. I'm going to give you an example that I hope will help you understand why this is unreadable. (You being able to understand it does not count as you mapped the song, you know how things work.)
(Yes i'm going to use osu! notes as an example as it's easier to understand.)

Take a look at this picture, see how the notes are placed on the grid and how the notes are placed in the timeline.
All the notes are even distance, this would make the player think it's all in one signature (1/1, 1/2, 1/3, etc) this applies to taiko aswell because when we look at the space between notes we think of them as a certin signature. But this issue is that the first 3 are a triplet 1/4 while the rest are 1/2, so without the proper distance all the player can rely on is the hitcircles. The same thing happens in taiko as all the player will only be able to base their judgment is when the note go to the hit area, they cannot determine when the note needs to be hit by the spacing like they
should be able to.
So do you see how this is unreadable and rather dumb this is to do now? Sorry if you still don't understand but I hope this example gives you some clarification.
