map notes
This is to illustrate vertical acceleration of some characters in the game. To test, stand (or jump) onto one of the three crumbling dust areas and then just let your character fall (don't move).

The orange area is the maximum distance that dustman and dustgirl fall without falling through the crumbling dust.

The green area is the maximum distance that dustworth will fall without landing on the crumbling dust.

The "garbage" are is the maximum distance that dustkid will fall without landing on the crumbling dust.

As you can see, dustman/girl cannot fall through any of the dust, while dustworth can fall through the long and medium heights and dustkid can fall through all heights.

whether or not you fall through blocks isn't determined only by speed.
the map notes suggest that dustworth/kid initiate their falls quicker than dustman/girl, but this is false.

EDIT:
After plenty of discussion I ended up just asking hitbox how it works, and it works as follows:
Dustblocks crumble under your feet if your velocity is 66%+ of your max velocity.
The acceleration values are as follows: Dustman/Dustgirl: 100%, Dustworth 90%, Dustkid 120%
The max velocity values are: Dustman/Dustgirl 100%, Dustworth/Dustkid 80%.
This easily explains why dustkid breaks the blocks the quickest: fastest acceleration while having the lowest maxvelocity. The reason dustworth is 2nd is because while he accelerates slower, he still reaches the 66% of his max velocity earlier, since it is lower than that of dustgirl/dustman.

do DG and DM really accelerate at the same pace? a lot of leaderboards attest otherwise...

DG initiates her fall earlier, which is why she still is overall faster than dustman. There's more info on this mechanic here:

I don't understand how she is overall faster than dustman, maybe I'm just confused. But they fall at the same speed, she just initiates her fall faster. But Dustman can always downdash in the air to immediately go downwards at max fall speed right? So how is she faster? I'm not trying to sound sarcastic or facetious I'm just curious cause I really don't understand the mechanic.

if both were to downdash at the same time they will go at the exact same speed. you can see this on construction site any% where they can both get the exact same time.

then look at exa any%, where dustgirl dominates the leaderboards because she is capable of initiating her fall faster than dustman.

Even with Exa I wouldn't say shes much faster, if at all faster, just more popular for those types of maps. Tiger10x is at #16 as dustman with identical times as all but the top 8 Dustgirls, and if I was a betting man I'd say dustman can complete the level at those top 8 times as well.

The more I think about it the only reason you'd want to play Dustgirl on an objective basis are the minor differences in her attack ranges from Dustman, I honestly cannot think of a reason her falling speed attribute is a positive thing in any situation because of how down dashing in the air works.

Gonna have to see it to believe it. According to Marksels tests dustgirl is actually around 4 frames faster than dustman in initiating her fall, though this could be different in the air. In any case 4 frames is not a lot but it can explain the small difference in times we see in the leaderboards.

edit to your edit - you may be right about the fact that initiating her fall doesn't make her "faster" all the time. I am just saying from a testing standpoint that dustgirl is just faster at falling than dustman when you ignore the downdash. This isn't really a way to judge whether one character is better than the other and they are pretty close in basically every area so if you took me saying "dustgirl is faster than dustman" as saying "dustgirl is the faster character" then my bad for not wording it better

After playing Exa a bit, yeah dustgirl probably is slightly faster there. In any case, I'm not trying to be argumentative, just trying to understand what you are saying. But I disagree with there being no way of judging which character is better, its just map dependent. For example in Kilo/Giga/and probably more similar levels, Dustman's hang time allows him to completely outclass Dustgirl since he can avoid getting caught on edges (halfway through Kilo, and the beginning of Giga), and it makes maps like Night Temple far less frustrating when you're jumping on the small platforms outside. I'm sure the opposite is kind of true in some levels (maybe archive and Tera and a few other dash heavy fall focused levels) for Dustgirl. Basically my point in all of this is that Dustman's advantage of additional hangtime is far superior to dustgirl's ability to fall slightly faster in the majority of maps available, which kind of invalidates the point of her being faster than him.

Edit: After reading your post a 2nd time, I think were just agreeing with each other at this point, so it's kind of a pointless discussion. So I'll just cut it here haha.
