Shift points in near stock C5 6MT?

I just ran my new-to-me 2000 coupe, 6-speed, at the drag strip and found that I was on the stock 6K RPM rev limiter about 20' short of the traps. I didn't have time to play with various shift points as I ended up only getting in 2 runs in about 6 hours due to the size of the crowd and the amount of breakage.
I am curious as to whether people ride the rev limiter or short shift into 4th. Pertinent info:
2000 coupe
6-speed
stock wheels
stock-sized Goodyear run-flats
only aftermarket modification is a B&B cat-back
shifted each gear just before 6k
ran 13.347 at 106.45 with a 2.10 60'
coolant temps at start of the run were between 190 - 200F
ambient temp was in the low to mid 70s
track is at or near sea level
