Very interesting.
No wonder this Tally Ho paper test requires the same level of keenness as the top hanging hair tests.
Any chance you can remember the source for its thickness being about 5 microns?

Thank you, Vadim

Mr. Vadim, 

The Tally Ho paper thickness of some 5 microns is not from internet, I have calculated it assuming the rolling paper volume density 750 kg/m³.

The formula is:
paper thickness (in microns) = 1 000 * paper weight (in g/m²) / paper density (in kg/m³) = 1000*4 / 750 ≈ 5 microns.
