Sorry I missed you. The factors are
14 1/2=1.93
17 1/2=1.59
20=1.37
25=1.07
30=.87
The info was found in the Van Kueren book "Precision Measuring Tools" under "Allowance for backlash"
These values will vary slightly on shaper cutters depending on the manufacturer and how far back they are sharpened.
