Jobo recommended a 5 minute pre-rinse at process temperature, then using the inversion time. You cannot do this with re-useable or replenishing developer because there would be some dilution.
It does depend a bit on the film and developer. The main thing is not to skimp on the pre-rinse time - you want to get the film saturated and stable.
if you go with the developer directly, you will probably see a little more contrast that a normal inversion every minute approach.
I pre-rinse unless I am using Thornton’s Two Bath developer.
Now wait for the counter opinions!
