Frame Advantage Issues

[Apep-the-snek]

all moves described are Captain Falcon's moves from here on out.
when i use a single hit move like falling up air, the frame advantage displays. but when i use only nair 1 (and not nair 2), it doesn't, could this be fixed in a later update to inclde multihits, perhaps also grabs?

1. Frame advantage is not accurate on hit
2. Frame advantage is not accurate on shield if the CPU is set to Mash OOS
3. Frame advantage is known to be 1 frame off in some circumstances (which?)
4. Frame advantage doesn't always display

If we can't fix these, maybe we restrict when it shows to on-shield only again?

• Set Frame Advantage to a non-number such as "-" when no Frame Advantage is noted to distinguish from 0
• Current beta frame advantage is mis-positioned due to being in the spot of Frame-by-Frame/slowdown UI
• Fix Frame Advantage methodology
