Bottom line: the calculated risks are a means to end to force a good Dhalsim to think more if you're successful to any degree. Learn what the preferable ranges are for whiff punishes / stuffing his limbs, when you could theoretically jump over them + land Mika's HK afterwards, be more irregular with your button presses or when you walk forwards -> block / opt for shimmies and so forth. It's an incredibly nuanced strategy quite frankly which will take some time to pick up on, but it's mandatory if you want to fight him in the neutral or outside the area where Mika can put people in the blender. The Mika mix-ups were, to put it bluntly, all you had going for you in that grand finals set vs Snafoo.
