yes/no... if you get them all say, within 20 seconds or less of each other, trust me, you can do this, then you can move them all into the water at the same time... let them sit in the dektol for 2.5 minutes, and developing should be the same between them, unnoticeable. when you take them all out, to the water wash, you can do so together. grab them all in one hand... drip them for 10 seconds.
