Intermittent soft 1-2 shifts at part-throttle

If the car is cold and I start driving it, the 1-2 shift is very harsh/firm, even though I am barely pressing the pedal.
Driving for about 20-30 minutes, I leave the car for about an hour. Start driving and the 1-2 shift seems softer than the 2-3 shift (at 1/3 throttle). However if I get on it, the trans never seems to let me down at WOT, nice firm 1-2 shift, screeching the tires almost every time. Eventually, part-throttle shifts start getting firmer.
Is this normal, or are my 1-2 clutch pacs going? I do have my shifts firmed up with Hypertech. Car has 26100 miles, last fluid change was at 22900 miles.

Not sure if it was coincidence, but I decided to "reinstall" the Hypertech with the same options I originally chose. Took the car for another ride somewhere and the tranny was shifting much better. The 1-2 shifts were still harsh when cold, but at operating temps the tranny 1-2 shifts were just as crisp as the 2-3 shifts. Seemed much more consistent in various throttle positions (1-2 and 2-3 feeling the same), and I was not able to replicate the "soft shift" issues yet.
EDIT -- Thought I would mention I don't have any codes going on (no SES light, and recently passed state inspection)
