Big improvement compared to the last time when you asked for advice on how to handle the match-up.
The one big takeaway from the grand finals set is that you gave up space too easily specifically in the matches where you convincingly lost. Not saying you should always go buck wild like you did in winners finals, where you got mileage out of it and weren't sufficiently deterred for choosing that approach for a while, but you need to strike a better balance like how you won some rounds in the GF set. To be more specific: backing off to create just enough space for whiff punishing Dhalsim's limbs with crouching MK (or whatever else comes to mind) and making a anticipation / offensive call afterwards through intuition or observations based on how your opponent responds is a good way to play the neutral game... but willingly (and quickly at that) putting yourself in the corner with little in the way of resistance is not. Dhalsim doesn't have that much in the way of pushback, so occasionally you played into his hands and gave yourself less options to work with when all he really did was standard poking while biding his time, in turn making possible outcomes more predictable. The one round where you lost with filled up V-Meter (plus a Critical Art locked and loaded) for example was largely your own doing; you sat in the corner preying for an ideal opportunity that never transpired, and it was a hard to read what your opponent could've been thinking (and subsequently react to his sudden aggression) when you hardly influence him, be it bait attempts or triggering any change in reaction.
To be more concrete: whenever you're retreating like that, reflect as to whether you're doing so for a planned (and actual legitimate) reason. Collecting your thoughts, deliberately killing time in a prolonged round, lowering stun, waiting for meter, avoiding mix-up shenanigans et cetera. Otherwise slowly push forward (making Dhalsim's limbs and drills increasingly less safe) or hold your ground the best you can if patience seems like a logical course of action. You evidently understood the general idea of how to make a Dhalsim second-guess and capitalize on openings, but from my perspective your in-game body language displayed less confidence during GF losses than in those from the WF set, which seasoned players such as Snafoo likely notice in seconds.
