Yes but is hard to determine the cruise point.
I will put in mu to-do list :)

Range 1.03 mm ~ 1.10 mm, but this is not really important
for me because given a constant weight (600mg) and assuming
a constant density, the section is inversely proportional to
the length, so when I say 'average' 1.35 mm is just get a
figure. Actually when I measure with I get oscilations +/-
0.02. What it counts for me is: a 600mg 8.5" lenght is a fat
section.
