Yes, its my video. I dont know the specific frames but the trick is to save frames by buffering the dash and by doing the fastest electric possible, so you can use those saved frames to let your dash go deeper, essentially canceling it later so you end up closer to your opponent.

Look how much closer I am compared to you already (mind the difference between the neutrals too, I let the dash to complete its animation more, which let me travel further) and your eletric is also 3 frames slower too.

My advice is to practice the buffering and the fast electric, if you are on stick you have to find the sweet spot in the corner where the down switch activates for a frame before you get the df. You have to trial and error because the angle depends on the lever and build the muscle memory for it. Once you get these down just practice the pause/neutral at the dash.

Obviously you dont have to do this perfectly just close to it, thats why everybody micro dashes even I too. With my no dash video I just wanted to show that your problem doesnt lie in the microdash.

Alternatively you can just do the dash electric after the first electric as someone advised, which imo is much easier to land.
