I have a question regarding the usage of dash attack in floaty matchups, such as Marth or Peach.
From past observation, there are 2 primary situations I have noticed it to be used.
One of them is when you are cornered.
To take an example from a Marth ditto
https://youtu.be/00kWf6lvDhU?t=6m13s (vs PPU @ apex)
You use it in the corner her after overextending. This was to catch ppu retreating? did you know he was going to dash back? I feel that dash attack is like a very hard commitment, considering the properties of the move, so it would take either a really good guess, or a good amount of foresight to know when to use it like that, especially in the corner. What I think the answer may be, is that ppu's back was to you, and he wanted to get out of that by dashing away, so you caught it.
Another example

Because you were coming from the ledge, I myself questioned this decision at first. This time, ppu has a clear stage advantage, and you go for the dash attack after pushing him away with ledgedash dtilt. Is this also because you knew he would try and come back in to prevent you from taking back stage?
I find it curious because it is used so sparingly in the ditto. In Marth vs Peach however, I see it a little bit more, to catch techrolls away and interestingly(or not), at the ledge.
Example (all from vs Armada @ Apex)

You go for it after getting a fthrow offstage. This is something that I have seen for quite awhile, but I've never understood the benefit of it, as I don't think it worked out for you very much during that particular set, which is why I abstain from using it like that, but I do want to know why it is used. I feel like it would be heavily DI dependent how this works out before and after the hit, whether you can follow it up or not, and if it misses, then you just might leave yourself open, depending, or be unable to cover their return if they go below the attack.

here you do hit the fthrow dash attack, and Armada airdodges away from your fair, which you manage to follow with a bair, and you punish his landing with fair. I only find it risky because it could have ended up differently if he had used his position differently, or managed to hit you.
Example of catching a techroll
https://youtu.be/IomXcdAAt7E?t=19m3s
You use fthrow and then follow it with dash > late fair. When Armada techrolls behind you, you catch it, yet he DI's far away form your followups. However, he IS at the edge. Maybe that's the strength of this option? Since you often go for fthrow > nair early near the edge or late fair like above, even if you can't hit them, they ARE in the air or far away, which is quite strong. I guess the only small issue I take with that is just the lack of possible followups at times, but I think I can see the strength it gives with such a large advantage (Peach in the air).
Are these situations the most effective uses of it, and is my understanding of the reasons behind them logical? Are there any other situations you feel it can be used, and why?
Thanks for reading!
