This is something I should have emphasised more in my original article, though I did say the agitation should be gentle.
To be clear about this, when I use a tray as described in the article, and when I use a Paterson Orbital, I lift the corners by the absolute minimum amount I can manage, i.e. no more than a few millimetres. After gently lifting one corner like this I move straight to another corner, lifting sucessive corners in a random fashion. The objective is to get the developer to move very gently. That way you get even development.

Hmmm... It hasn't happened to me yet Alan, but I do use 1:100 and 1:500 working solutions of my favourite developers. I also pre-soak for 5 minutes in water before going on to developing. The lift and put down isn't violent or quick, so maybe that is why I get no uneven development?
