Patrick,Patrick Johnson said:Actually, neither of these statements is correct. Backhand english can't correct for swerve because swerve varies with every shot; it can only correct for squirt, and then only if your shaft's pivot point is at your bridge.
But squirt never happens without swerve, so BHE pretty much never works exactly. It's another "approximation system" like CTE aiming (and most other aiming systems) - it gets you in the ballpark, but you have to finish on your own.

That's true, in a sense. The BHE system, as known does not account for swerve. There is an adjustement system which I've seen mentioned originating from Efren. It is simplistic in that it says avoid slow IE and aim 1/6th inch thicker when using OE.
These are ok guidelines but far from comprehensive. There are exceptions and much of the time this adjustment method is a matter of near enough good enough, unless you get a feel for varying this adjustment.
This adjustment method says nothing about distance which is crucial. The effective pivot point can vary by 6 inches between a close and a distance shot.
This thread here discusses the effective pivot adjustment system I developed for those interested. http://forums.azbilliards.com/showthread.php?t=116815
I figured on calling my method the Aim, Pivot, Throw System, to differentiate it from BHE, though it is an addition to that system. I think BHE is slightly misleading anyway, because many people assume it is a type of english, rather than an aiming system for using english.
Note also that any adjustment system needs to take into account throw. I discuss this a little in this post where I include one of the throw maps that I use to determing throw when applying BHE in my system:
