Its seems you have been moderate at doing this though. Your throttle modulation helps with the strain on the clutches with that type of launching.

I wish I had a way to see my 60' to say one way or the other from the event, but I don't. My impression was that they would have been very nice actually. The car was launching beautifully. I had full grip and was WOT within 10-15 feet if I was to guestimate. I see what you are saying with the over-heating though if the DCT is only applying with half pressure with that method. Sources for that fact would be greatly appreciated!
I did five launches in my autocross runs and 4 of them were with the method I described. Within the number of launches and amount of time I had between though launches, I didn't have any slipping problems, but that's not to say it won't happen later.
