The agitation is set by the Sidekick, I haven't measured the rotation rate, but it seems pretty adequate. It is also not something I can easily adjust.

Oxidation... that is a good question. I use the chemicals one shot, so they are poured into a Jobo bottle and then I have PVC tube plumbed from there up to the multi-selector on the back of the Photo Therm. (So it is not as sealed as it would be if there was no tubing and was airtight, but the chemicals were mixed fresh 2 days ago.)
