Replacing collimation screws 180 Mak

I jumped in the deep end with this (fools rush in...) because I need to know how to collimate this scope so I can squeeze every bit of performance out of the setup. I've figured out that it's 3 pairs of push-pull screws, rather than 3 sets of 1 adjustment screw and 1 locking screw. When I started I noticed all three pull screws were tightened all the way in, drawing the the mirror right back, which made me wonder if this was a setting for shipping to stop the mirror moving. The full range of travel with these pull screws is 10 turns, so I started collimating with them set at 4 full turns out. I think this has resulted in the mirror being a few millimeters further forward than before, and I think it's made an improvement. It'll be interesting to see how it all settles...
Cheers
