seems accurate, but i'd like to make a few objections

is not F tier, if you use his side special to air stall, you can get him to E tier at best, maybe D tier.
using

's f-air, you can get to D-tier easily
i (somehow) got

to D-tier
using up all of

's recovery moves and jumps and just gliding to the end, he can get to A tier.
sheik can make it to C-tier with dangerously low jumps and bouncing fish
i guess

's placing was reasonable, but you can get him to A-tier if you use side special, then midair jump, then up special.

is B-tier, use down special a second time only after your midair jump.
using

's neutral special rather than the other specials will get him to A-tier

is A-tier, using his jumps dangerously close to the ground to get distance can get him there.
down special > up special > down special > side special> up special & repeat can get

to S-tier
and i
think that's it. as i said before, it was pretty accurate, good job. maybe you could apply these to the list.
additional notes:
peach can make it to the blast zones
pichu and discharge pichu make it to the same rank
tails can almost make it to S-tier
sheik can almost make it to B-tier, i had brushed off the C-tier platform by just a few pixels. bandana dee's strategy doesn't work in this situation.
