jensm, To answer your question most of the manufacturers have set up profilometers to measure surface roughness the exact same way we do. In fact, in the last two months, I have been to a ball plant to help with their setup and another manufacturer came here to see how we do it.
Unfortunatly, since we charge the manufacturer's to approve their new bowling balls, it is their data and it is up to them if they would like to share it with the general public.
Hopefully this answers your questions.
