I'll agree with Humaround in that you seem to be confusing approach speed with touchdown speed.
For a Pitts S-1, the approach speed I always used was 90 mph, but I can guarantee you I never touched down at that speed. At what exact speed I DID touch down I cannot tell you because I never looked - far too busy at that moment looking at other stuff going by at some unknown-but-still-pretty-fast speed. However, since the Pitts stalls at around 60 mph, I'm guessing it was somewhere between 65 and 70 mph.
