Who needs information to make a logical decision these days?! Just, make your decisions without looking at all the information that is potentially available, seems to work for governments throughout the world! Ok, sarcasm switch now turned off.
I find it hard to see how one can logically come to the conclusion of 'if I can't do it, then no one should be able too'.
Information is power, how you use or don't use that information is up to you. But preventing such use because a few refuse, is just plain ridiculous.
The 'I learned how to adjust so why can't everyone else' theory is as old (and tiresome) as the days when that theory was relevant. Sure, oil was placed on the surface with a spray can and smoothed out with 'mops', but you also only had a few ball choices too. Black 15 pound or black 16 pound. Which to take?!? (sorry someone switched on the sarcasm switch again! I'll turn it back off.)
With the variety of patterns and angles available it is at the stage that over 20 balls would be needed to counter all permutations that you could be faced with. QANTAS would be having an orgasm right now reading this!
The pattern will never play exactly as the pattern says (oil is still a fluid after all), but it does allow one to cull the 20+ balls down to 4-6 (with some confidence that those balls can be used throughout the tournament format - with adjustments between ball changes!
).
And yes, (excluding the few lefties out there
) adjustments are still fundamental to the sport - even in the 21st century. If one could bring 20+ balls then sure adjustments could be a mere 2-5 boards like the old days, though adjustments can now be 25+ boards before a change of ball is
required.
Wonder which era, really can boast the 'I learned to adjust' badge?!?
