That uses abrasive?
The base in the test lenses is 5 +/- 1?
What value of Haze get on CR39 lens? (Usually must be between 13 and 17)
I personally found problems in relation to the efficiency of the abrasive oschillazione system, often a maintenance in oscillating system makes the movement less jerky and thus the acceleration of the abrasive on the plate changes.
Note: with the last batch of abrasive I found a decrease of needed results from 14 to 6, but remember the Bayer don't give you linear result... the difference betwen 10 and 15 is not like the difference betwen 5 and 10
let me know
