And, having instructed at Wallop on the Gazelle, I know you are getting confused as Shy says.
A zero speed auto is used when you are close to your only available (or least worst) landing area - bringing the speed back allows you to keep the point in view as it moves up the windscreen. When you judge the aiming point to be in the right place, you adjust the speed back to 60 kts (in the Gaz) ready to carry out your variable flare EOL.
A constant attitude EOL was flown at 35 - 40 kts and could be quite steep if the wind was strong (but never backwards) - this was used when you couldn't get enough speed for a VF EOL or when one was an unsuitable choice (night reversionary for example). They could look scary but were quite straightforward and lots of fun.
As for finessing entry to auto - you are talking about recovery from VRS which, due to the rapid height loss, doesn't really allow for finesse - if your normal auto RoD is 2000'/min and your VRS RoD is 4000'/min getting into a proper auto/windmill brake state is going to be tricky.
The advice on lowering the lever in VRS is to try and unstall the root and lessen the tip votices to give you some semblance of control - it doesn't have to be all the way to min pitch.
