Excellent post Martin.
I agree with Martin, the only difference is that I look at the tail and I also start it with a right forward elevator motion when the tail is facing me that becomes a clockwise stirring motion. The reason I do that is that I want the helicopter to enter the maneuver going away from me instead of towards me.
The issue that confused me initially was that looking at the tail or nose when it faces me is good but it reverses when the heli goes inverted. So you have to keep in mind that when inverted, to keep fliping the disc in the same direction, you need to either wait for the tail or nose to be away from you and start the inverted part of the maneuver the same way or wait for the tail or nose to be facing you and start the maneuver pulling instead of pushing th elevator.
This all works when you're doing piroueting flips that are and look in reality like a succesion of half piroueting flips. For continuous ones you need to keep your eyes on that tail/nose and constantly make timing adjustments.
A problem that sometimes happens when you're doing continuous piro flips is that when missing a beat you might end up flipping along a vertical axis sort of like doing a piroueting death spiral.
Don't panic just slow down the "stirring rate" until you see it come back to horizontal discs and then resume the stirring rate. Trust me this trick is worth its weight in crash gold 
If you're trying this on a simulator make this adjustment:
Edit the heli and go to the tail rotor. Change from say 10.5 inches to 11.5 inches in diameter. You might have to lower the gain of the gyro so the tail won't "hunt" and adjust the piro rate so that you can initially try it with full rudder deflection (one thin less to worry about). It will give you tail authority to keep a constant piro rate. The same works in real life. As Martin said before a constant rate of piro is a must for this maneuver.
Now can anyone answer my question about the rolling circle?
