Yes, swerve is the most difficult of the "aiming variables", due to its dependence on so many other variables - amount of spin, shot distance, shot speed, cue elevation, cloth/ball conditions. Maybe more?
Throw also depends on several variables, even though it's a smaller effect.
I agree that squirt, even though it's the largest effect, is the most predictable of these and so the easiest to deal with - but it's the one we can improve with equipment, so why not do that?

You can improve upon it so you should improve upon it.
My issue lies with the push for ever less deflection and the ensuing marketing pushes telling everyone that the old one wasn't as accurate as this new one, implying that you need this new one.
Do you think a 1 or 2 percent decrease in end mass makes a shaft far more accurate or impercievably more accurate? That's the range of improvement thats being pushed by the mfg's as near miraculous breakthroughs.
It has been my experience that a high squirt cue gives more than enough margin for error, sure low squirt shafts increase that margin, but I'll never be convinced its necessary. To each his own.
I've had many conversations with many players of all different levels about deflection. The amount of people who have it in their head that they need a different shaft to improve their game is mind boggling, even some very good payers who should know the real ways that they can improve.
