I have always been a bit of a freek with the amount of chems.. I always use 1000ml no matter what process.
It takes me about 20 seconds to dump and refill. Thats all I have been doing for the last 7 days so it does take that long for me.

Since pushes with e6 don't require really long increases (like many b+w films) you may get away with standard amounts. After all, the time it takes to dump/refill the drum is how many seconds?_
