As an Orbital user, I am really interested how you do agitation. Which kind of pattern and how often.
I have abandoned the motorized base and now I use Orbital like a slosher, rocking it from each side. Doing two full series of rocking in the beginning of each minute. The one serie is: raise from nearest side, then left, then back, then right.

Usually this gives a good negatives, but sometimes there's a little more density on the edges.
I don't know if it's caused my agitation pattern, speed or something else. I too use 300 ml.
