Default RPM Drop and Converter slip%

So I was looking over my files of that 9.56 run. My RPM drop was 400 rpm's between 1-2 (6200-5750) and 550 rpm's 2-3 (6300-5750). Is that around the norm? Or should it be a steeper drop?

Also I plugged all the #'s in on the TCI website and it came up with 6.71% of slip.

6450 rpm's, tire height 29, rear end ratio 3.42, trans ratio 1.1, mph 138.67.

I think that is pretty much right on. For the tire height I even put in 29 to compensate for tire growth. I checked M/T's website for slick growth and they stated @ 150 mph that the tires grow up to an inch to an inch and a half. My slicks are at the end of there cycle so I that's why I plugged in 29.
