Mapping with very minor BPM changes.

is there an easy way to keep consistent DS with tons of really minor timing changes?

In general how do people map these types of maps to be consistent and comfortable?

Any input on this is much appreciated. Maybe some examples of modern maps so I can study how they mapped around the timing changes?

Idk, most people don't use DS aside from like doing streams by hand or manual stacking when it comes to higher diffs. Music is always coming from somewhere or going to somewhere so often times focusing too much on making everything in you map "consistent" with itself is losing sight of the end goal. If your map is truly consistent with the music it will also be consistent with itself but not always the other way around.

If you just want to do things like make 3 consecutive notes be spaced as an equilateral triangle regardless of a red line in the middle of them then you can always just make the pattern on one bpm and drag each circle into the correct place on the timeline once you've finished. You can also just place circles and copy/paste/scale/rotate as needed to get your desired patterns/structure going. Getting SV's to match is a bit trickier since it scales with bpm but this is kind of an example of consistent with the music as opposed to simply consistent with itself. If there is a sudden/significant bpm change it should probably be reflected in your sliders anyways.

Some examples of maps for songs with numerous bpm changes:

You probably want that your map has an equidistant spacing but the variable bpm screws it because DS scales with bpm.
Best advice I have is toggling DS off and using the grid as a mean of orientation when placing notes.

I think he means easier diffs where you have to use DS

In that case, it really depends on how much the BPM changes.
But the DS has to change according to the multiplyer:
Say the BPM was 170 till now and it changes to 85
That's exactly half of the BPM it was before, so you need to galf the DS imo
It does get trickier with stuff like 170 -> 56 but you have to find the DS out with math then like the previous example

You technically don't have to use DS for lower difficulties. You just need to maintain "consistent" spacing. It's important to note that consistent is not even the same as constant (which is what DS attempts to enforce). Consistent basically just means "within some acceptable level of deviation" but that level of deviation is an entirely subjective matter (thus why we have BN's as opposed to letting an improved AI-mod push forth verdicts on ranking of maps).

True, but staying on topic:
When BPM varies DS has to be in a way that a beginner can comprehend the DS change if any
