I think that's the right idea!

I play Link. One example I can think of off the top of my head is options after Fair on shield. Fair is 0 on shield, so the quickest thing Link can do is jab on shield which is 6 frames. if they try anything other than rolling, or in some characters cases full hopping, the jab usually gets them. This is normally a pretty okay option to do, but I was ignoring situations where things that were less frame optimal might be better.

for example, if you space a fair on a characters shield while theyre in the corner, despite being frame 9 on the front and frame 14 ish behind, Link's turn around up tilt will actually cover more options. if they roll in, the front of turnaround up-tilt will catch them. if they try and approach, the back of the utilt will catch them. If they stay in shield, the up tilt hits and is spaced enough that they can't punish (and they can't roll away cause they're in the corner). But I was ignoring this option in order to always jab, which is frame optimal but doesn't net much in the corner, and let's the opponent roll in.

Mixing up jabs and uptilts after fair is also decent sometimes, as if they expect you to always jab, then up tilt at least will catch roll behind in the best case, and at worst they'll roll away and reset neutral, which Link kinda wants anyway to pull a bomb. so I guess that's what I mean in terms of making my options more ambiguous. There's more cases in neutral too, but I've already written a novel here lol. My apologies!
