maximize shift points

I went out today to see what real life rpm was. It is very hard to simulate track conditions since I was on street tires and it's very hard to get any rpm under heavy acceleration without spinning the tires. It is very different on mid acceleration and hard acceleration. On mid acceleration - not hammering but steady accel:

1-2 shift at 5000 rpm dropped to 3500 rpm, 2-3 at 5000 rpm dropped to 3800 rpm
1-2 shift at 6000 rpm dropped to 4000 rpm, 2-3 at 6000 rpm dropped to 4400 rpm

On hard acceleration, pedal hammered, I couldn't get a 5000 rpm shift. It blows through the lower rpm too fast. I had a hard time getting a look at 6000 rpm and I probably shifted closer to 6500.

1-2 shift at @6000 rpm dropped to 4800 rpm, 2-3 at 6000 rpm dropped to 5000 rpm.

So, what are we thinking with this new info? I am thinking a higher rpm 1-2 shift and maybe a little less than 6000 on the 2-3. I never really needed to kick into overdrive, I just stayed in 3rd until I crossed the line.
