It isn't hard if you're methodical and patient. Keeping the temps steady isn't hard, you just have to think it out. It is a LOT easier when the ambient temps are steady. Jobos can be good, but if you can't get it done by hand, you can't to it with a machine ! If you want to do a lot of it... that's different. The multiple use regimen is pretty fool proof, Kodak sorted its data out pretty well.

Good luck !
