In fully developed VRS, #1 will lose less height. Raising collective will 'deepen' the VRS.
Having lost 6500ft in an out of control Puma due to VRS, I can tell you categorically that in my experience, the Vuichard technique is bollocks. My VRS was so well developed that the cyclic had no effect on aircraft attitude, even at full deflection. I'm convinced that the only reason we got any speed at all to fly out of the situation was due to the very high RoD resulting in an upward force on the horizontal stabiliser thus pitching the aircraft nose down. The cyclic did bugger all, despite trying to force it through the instrument panel! Lateral cyclic would have been cock all use.
