C41 developers should all use 3 minutes 15 seconds with a fresh/working solution. On the second and third rolls for each unit of solution you should increase time by 15 seconds each for 3:30 second roll and 3:45 third roll and then discard.
I use 30 seconds continuous and 4 lifts every 30 seconds thereafter, so yours works fine. I pour in the chemistry slightly warm to compensate for the loss over the initial 30 second agitation. I also use a pre soak to get the temp up. Temp doesn't appear to be as critical as said. I keep the water bath at 101-102 because according to my **highly** scientific tests this works about right with my agitation.
With my tetenal development, I have found it to be very counter productive to increase the standing time at this rate. I am at roll 28 and I am only at 3:30 dev time.
I agree that temp too high doesnt seem to hurt - I ususally run at 39-40C for the dev.

Roll 28, wow! I bump the dev time up just a bit later on, works for me but not much or highlights block up. 39-40C here too.
