1. The recommendation is to always separate generators running the same program by 5 minutes. The M&L Protocol has 3 generators running the same program with the offsets. I think the limiting factor will be how much herxing happens. You'll definitely want to keep some maintenance running along with however many generators you decide to run.
2. Most of us do not run our generator in that manner. Not saying it can't be done. If you research the protocols bundled together to assist us, you will not see that. Check that out and decide for yourself.
