Stijloor,
I do not have the 4th ed. yet. It is on order and I should have it in a few weeks.
From What I have read, about the only major change to the ANOVA GR&R was 5.15 changed to 6. I just looked and the file I attached and, OOOOPs, I have already made that change, I forgot to change the file name to V4, my bad. The changes are on lines 66, 67, 68, and, 70.
