something odd

[mariofanpm12]

so i wa sin training mode and i used ganon's fsmash, not aimed up or down, just straight. It did 33%, like always. i sed it again, though, and the foe's % when from 33 to 67%, which would mean the move did 34%... but the Help bar (which I know is innacurate) said the move did 33%. I tried again and the daamge went from 67% to 100%...so it had done 33% again...

After resetting the damage and doing this again, the same thing happened. Any explanation for this?

attacks have base damage, but occasionally do up to 3% more or less than normal, which is the showed damage.
...maybe.

That or 1/2 damage.

Some attacks do fractions of percents of damage. This actually makes a difference, as any attack that does more than exactly 7% in one hit can knock Snake off his Cypher. This means attacks that do EXACTLY 7% do not work, like Mario's D-air final hit IIRC.
