OK. So, sometime, and for either real of just accepted reasons, the rear tire will break loose. Now what?
Pull in the clutch. That prevents the "tankslapper" behavior. The rear tire either will or will not regain traction. If it doesn't, you Low-side. If it does, it will do so gently, and not "loose it again" because of the decelerative traction demand closing the throttle, or even holding it steady will make.
Why not just hold the throttle steady, or "gently roll off". Either might work - the operative word being "migth". Great riders, like at the top level of racing, have experience in "saving slides". But they still fail. Every High-side witnessed resulted from failing to effectively handle the initial Low-side forces - as did every Low-side too. You gonna do better than they do? At night? On a wet road? With no heated up rain tires? In the cold?
Good luck out there, guys. And good technique too.
