The larger the hole in the disk, the more repeatable the charge weight is going to be. That's true with pretty much all flake powders.
I was using my Lee disk measure with Unique to reload .32 Long ammo many years ago. At something like 2.0 grains of Unique I was getting HUGE variations in load weights.
That's pretty much when I gave up on Unique. 231 was my standard, and it measured great no matter what the size of the hole in the disk.
