I think consistent dot gain is far more important than the least dot gain. We are all using different ink/blanket fountain solution combinations so with your press properly packed and your materials in spec the dot gain numbers you get are your own numbers and as long as you can consistently achieve those numbers day to day then you can adjust the other processes accordingly.
just my opinion folks

Dot gain is a process control metric - it is not a target.
The target is a tone reproduction curve embodied in the print standard or specification you want your presswork to align to.
Whatever dot gains get you to that tone reproduction curve are the dot gains that you need to maintain in your printing.

I never know when you're being sarcastic or direct.

In my experience, most printers don't understand the context of dot gain, and as a result they make production decisions that may result in less than optimal results and/or wasted time and resources. The OP's question appeared to me to be such a case.

Perhaps you have a better insight?
