Trying for 3280 ft with each character in HRC... need some help

[yawgtwo]

The main HRC challenge in the game was to get 3280 ft with a character.
Obviously it's super easy to just smack it like 7-8k with Ganondorf and be done with it.
Buuuut! I wanted to challenge myself to do it with every character. Some are harder than others...

A lot of the characters were super simple.
Grab bat, dash attack, then stand next to it and smash throw the bat down and hit A as much as you can.

Others had more complex strats but all-in-all still reasonably easy.
The ones I have left are characters who can't do the easy BTD thing or characters that have very slow timing for that and ones I simply cannot figure out how to get like 120%+ on before time is up. I was wondering if anyone can help me out with some simple strats (not WR ones haha) for the last 9 characters I'm struggling with.

Peach - 3062.3
Wario - 3035.7
G&W - 3266.0 (UGH)
Zelda - 2929.4
Dedede - 3257.2
Meta Knight - 2867.4
Pikachu - 2970.8
Charizard - 2914.6
R.O.B. - 2970.8

Thanks to anyone who might be able to help me out.
If you want to know what I've been trying with a specific character just ask. I can make a vid or something.

How did you get over 3280 ft. with Rosalina? The farthest I've hit with her is at around 2300 ft.
