Why I went the way I did:
Tail rotor effectiveness or not, unless I'm missing something accelerating the airflow over the disc is key. Just booting the tail out wouldn't cause an acceleration. Given it's supposed reference in the R22 manual (wiki source, I have no truth data) it seems more a link to getting the disc tilted rapidly without getting negative G and the associated mast bumping problem. If I were concerned with mast bumping and felt the onset of VRS, I could make a faster recovery with this technique just based on time to get to say 20 degrees of tilt. I guess I fail to see what cross controlling does different than shoving the nose into the dirt. Both rely on having some level of cyclic control remaining, just a different axis.
Not trying to be a snarky smart ass, I swear.
