I was using my scraper on some QLD Walnut and I found the scraper produced what looked like it was a higher equilavent grit to the 1200G I was using.
I the did a couple of tests to follow up my curosity to see if I could find out the answer myself
Shot No 1 using surface refelection as a gauge Timber on the left is Jarrah.
Shot No 2 using surface refelection as a gauge Timber on the right is Pine.
Surprisingly The results displayed something less than 1200 G if you used the refelection method as a reference
Using the calibrated finger the 1200 felt smoother than the scraper.
So is there and answer to this puzzle?
