Poker pot odds calculation: does anyone actually do this mid-hand

everyone talks about pot odds like they're doing the math in their head right in the middle of a hand, but is anyone actually breaking out calculators or full math while the action's on them? for me, in live games especially, i kind of run off feel and rough guesses, not exact numbers. i know my basic outs and try to eyeball if the call feels close, but i never feel like i have time to crunch it out for real.

does anyone here seriously calculate full pot odds on the fly, or is it just all vibe and experience?
