I believe that was Ronnie's old method. I believe he had adjusted it ( due to feed back) some time ago.
As for Machine. I think you should give it a run. Not for sure why guys fuss so much over prop. Is it that much better than E? I know there is a bit more Test to ester ratio with prop than E, but E is so much easier to use. Less pins, less pains, less problems. Ronnie seems to recommend it a lot over prop as well.
Good Luck Guy
