OK, I'm going to need some ed-cation(my spelling, Jack).
You've got your trick, plywood friction gauge all set and quantified. You are going up and down the return road, can't get closer to the track than a couple hundred or so feet, taking readings and putting them in your laptop spreadsheet. The actual track surface has had dozens of runs on it over the last few days so it has no relationship to the return road. In the meantime your buddy is advancing your roadster thru the lines to the starting area.
In a couple of hours you have the info you need and hustle back to your car which is now three back and needs a driver suited up and ready to go.
Scott has been dumping some of his low power bikes out of the trailer and quailfying for a couple of dozen records. Now, here is the trick part. We know Scott has his finger on the cof of the surface today so while pulling on our firesuit we sneek a glance to see what he has in mind. There sits a 4 turbo, multi cylinder, many streamlined, fuel bike ready to go.
Oh my God!!! my data is wrong!!! You jump out of the car, wave a couple of people around while making whatever adjustments you think will be to your advantage. In the mean time the temp has fallen, the clouds and wind have come up and what data you have in your spreadsheet is junk.
Please tell how the cof reading from several miles away and hours ago will help during your 2.5 to 3 min of run time.
As always, in wonderment of overthinking this thing,
