After some research, running sims, and modifying a couple of strategies to understand this subject better, I hope I have it right.
Betting “granularity”
Here comes this awesome 11 letter word. “granularity”. According to Wikipedia: “Granularity is the extent to which a system is broken down into small parts, either the system itself or its description or observation. It is the "extent to which a larger entity is subdivided. For example, a yard broken into inches has finer granularity than a yard broken into feet."
After much reading about this on these boards and looking up the technical meaning, what exactly does it have to do with BJ?
To those who have just read through the word and all those other posts and didn’t care what it means, I guess you’ll skip this post too. To those interested keep reading. For those who can explain it better then I can, please help out. If I’m wrong in the explanation go ahead and blast me.
So when does “granularity” come into play?
Many times the word comes up when we discuss 1/2DTC, 1DTC, or 2DTC. In expanded terms this means when you convert the RC to TC. Some of us use ½ D TC conversion, 1d TC conversion, or 2d TC conversion.
The easiest way I came up to explain it is this:
Let’s say your strategy uses 1/2DTC. The current RC is 6 with 3d left to play so your TC=1. If you change to 1DTC which also requires you to double your indices, the same RC of 6 results in a TC=2.
When we run a sim using the 1/2DTC and look at all the TC’s both negative and positive generated by the sim it produces a range. Now lets say the range of all TC’s that come up greater then 1% of the time will be between TC-6 & TC+5.
Taking the 1/2DTC as an example first, for the sake of ease we can say that in the optimum betting strategy there may be 5 steps in our 1-12 spread betting strategy.
For example TC0=1u, TC+1=3u, TC+2=4u, TC+3=6u, TC+4=10u, TC+5=12u
Using the 1DTC as an example, the new range of TC’s that occur may range from TC-9 to TC+8. The optimum 1-12 betting strategy will now spread out your bet spread over a larger number of positive TC integers. For example:
TC0=1u, TC+1=2u, TC+2=3u, TC+3=4u, TC+4=6u, TC+5=8u, TC+6=9u, TC+8=10u, TC+9=12u
In this same scenario, going to 2DTC would require you to change the indices accordingly and would increase the number of steps in your betting strategy yet again.
So what does this do for us? After close review it does this: It allows us to bet closer to the true advantage we have at the time. The less jumping of bets we do as we go up each TC, which in definition “smaller parts”, prevent us from over or under betting our advantage.
So I thought, what if I set up my betting strategy by ½ TC steps. Unfortunately it did not produce the results I had expected.
My conclusions force me to admit that there are real benefits in “betting granularity”.
