That occured to me after my last posting, but I can't think why it wouldn't
slow.

Yes, your right.
I've switched to the 10x Swan firmware, and stored the results in the datalog.
Here they are
Variable 4: 4
Variable 4: 0
Variable 4: 3
Variable 4: 0
Variable 4: 7
Variable 4: 0
Variable 4: 5
Variable 4: 6
Variable 4: 1
Variable 4: 4
Variable 4: 0
Variable 4: 6
Variable 4: 2
Variable 4: 5
Variable 4: 0
Variable 4: 7
Variable 4: 0
Variable 4: 5
Variable 4: 0
Variable 4: 7
Variable 4: 1
Variable 4: 5
Variable 4: 0
Variable 4: 9
Variable 4: 0
Variable 4: 7
Variable 4: 0
These are the timings of the gaps between rotation sensor changes using just an
incrementing loop, not an RCX timer(for those new to this thread).
Basically the variable timeout in the code I posted previously. They should get
progressively bigger.
