Route North.
B1; 100 - 95 - 81
B2; 100 - 97 - 82
A1; 100 - 92 - 80
A2; 100 - 93 - 80

B2; 100 - 96 - 82
Route South
B1; 101 - 61 - 50
B2; 100 - 59 - 48
A1; 100 - 58 - 45
A2; 100 - 58 - 45
B1; 100 - 60 - 50
B2; 100 - 60 - 49
B2; 100 - 60 - 49
It looks like the kammback is doing it's job. The road wasn't really sutable for faster testing, but that would have been better I think.
Next thing is tuft-testing, but that will have to wait until after the 2000 mile trip.
