^ that's the m2k training strategy lol, works well but you could just do it during friendlies which is more entertaining. try changing your timing until you get it, and make sure you're doing both the greystick and cstick
i have the same probelm of dd'ing far away, for me it's a falco habit i think because falco's run is very slow he's kind of forced to dd farther away to compensate for fast opponent, otherwise he just gets run over by fast chars. thankfully falco also gets to retreat to platforms really fast and has lasers lol
it's part of why sometimes i prefer smaller stages for pika even though the general consensus is that pika wants more room and that ys sucks for him. i think that only really applies against slower characters, and against faster characters you don't want them to have the option of running whenever to a safe space with their back to a mile of earth or something
i also have a problem of being predictable with nair, and at that point i have to do really stupid/weird approaches like fh dair or sh waveland or something equally stupid (depending on what they're doing) and that's when i start getting frustrated at pika lol. i wish he had more genuine approach options that weren't gimmicky. my favorite gimmick approach is running sh uair where the front of uair reaches in front of pika to almost give him more priority
overextending approaches doesn't really work vs fast characters with good dds if they have space, so like fox/falcon/marth can easily outspace a very overextended nair by reacting to your commitment with space>attack. you kind of have to force them near the edge or to an uncomfortable position (usually in a way so that they can't dash out of nair trajectory/are above you) where then you could sort of mislead them into reacting...but that feels really lame <_______< plus at that point nairing isn't the best punishment anymore, might as well just cover with grab or dsmash
it's all very frustrating
if i could just stick to my opponent like fly on **** then i'd be happier lol. but first i gotta work on my dd'ing.
idk im just impatient in general and always want to be doing something lol
im also really tired so parts of this post might be really badly written
