Back in the day when I was playing fairly high and it was not uncommon for road agents to take a shot at me as I always was ready to play
I found that the only way I could gage the speed was after Ikept adjusting every time I lost a few games over and over.Then sometime it took until I was bone dry and some rail bird walked over and told me that they thought I knew better than to play Vernon Elliot,or Craig Stevens or St Louie Louie or Norm Hitchcock or Arkansas Calvin or Mike Massey even when he played onehanded
These after the fact revelations always helped me to gage the speed after I was dry. Now if the question is"How do you gage the speed before losing my money?" That is a thing that eluded me for years,and i can't say that I ever figured it out
As a matter of fact,I have had the same trouble with Billy Incardona for several years now,the first time I played him some 25 years ago,he was nothing special at one pocket so I only got 10 to 5 and the break,He had never played me either but based on advice from the local pool deectives he gave me this huge spot. I thought I had the nuts ,but he actually had the best of it,so I was free stroking,thinking who cares if I win this game,the nuts will save me over the long haul
So I shot at my hole every chance and everything i shot went in or lucked something in or hid the cue ball accidently .After several games Billy paid off and mumbled something about a double steer to the detective little knowing that i was blind hog lucky
Well,the lesson is if Billy Incardone could not tell my true speed,who could?
