Seams to give 1/2 to 2 thou runout (Clamp once get 1/2 clamp again get 2) from 1/4 to 1 1/2 stock.
Checked the 12 inch 3 jaw Bison on the Summit. The marked pinion gives about 3 thou runout but the next one over clockwise it drops to 1/2 thou on 1 1/2 inch stock.

Free advice is worth exactly what you payed for it.
