Contrast issues with Paterson Orbital?

It works reasonably well. So I thought, until I found until someone told me that I could be losing subtle contrast variations.

I use HC110 - which I believe is also somewhat sensitive to constant agitation.

I agree with polyglot - testing is the key, especially if you are knowledgeable about densitometry.

I usually use PC-TEA in mine, at 1+50, and use around 150ml of developer solution. This does four 4x5 sheets without problems.

I have tried with more solution (like when using Rodinal), but found that using much more than 200ml lead to spillage.

I use it on the base and complete one wobbly revolution every 2 seconds or so, changing direction every 30 seconds. I've not noticed any uneven development or contrast problems.
