Re. the cruise control - did you set it once and leave it "on" for all A & B runs, and just cancel it with the brake?
yes, the whole test is "on the fly"
when I enter and leave the course - the only thing I touch is the scan gauge
I found that any other influences created too much error - even a brake tap
everything is setup and in place at least ~1/2 mile before I start taking data
it helps the ECU settle in to cruise
If I had made the pre-run longer - I probably would have fewer asterisks
but it took long enough as it was

I haven't run standard deviation calculations ( I have an aversion to statistics )
but I have gone this far - I guess I should dust the brain cells off and just do it
Start where you are - Use what you have - Do what you can.
