In post 155 "When trawling through a number of Tables each containing a maximum of 28 spins from my model". I therefore trawled through over 100 cards containing 28 spins from over 100 Tables from various casino's. I am assuming you haven't read all the previous posts, so to recap, I go to a casino record 28 spins. no more at that Table. I then move to another Table and repeat the process. Moving from Table to Table you can then accumulate the spins 28 + 28 + 28 + 28 = 112 an example of a possible sleeper. Deduct 56 and we have a parameter 056/112. Add on another 25 spins from the next table and we have a 137 spins deduct 56 gives a parameter of 081/137. If you intend to do this yourself, I am assuming you will use a PRNG. I don't know if this will work or not. If you do I will be interested to see the results. It is important to limit the spins/numbers to 28. I would suggest reset after every 28 numbers, hopefully that will work. Nearly forgot 56 & 28 spins comes about from a great deal of work, trial and error trying to find out what works and what doesn't. Would not want to do it again.
