While this shoe has an overall -2 OR count the OR count actually hits -15 in the 3rd col. This points directly at our System 40A streak component systems RD1 or F2 and rules out 40 completely. So now the question becomes WHICH streak system? Well, we know that RD1 hates 1's so RD1 is ruled out right off the bat. We also know that F2 LOVES both straight and ZZ runs as well as sporadic 1's and this shoe is chock full of all 3 right from the get go. Even if you had no clue at the beginning of the shoe it starts with a ZZ run of 5 followed by a straight run of 7. A half way alert player would be onto F2 somewhere during the straight run of 7. But a shoe this streaky does not come out of no where. It is highly likely our player would have been onto F2 even BEFORE this shoe began. here is were I get lost 1 were can I find this F2 system? 2 this wast taken from the 40 manual A - OR count means we start with one of our two streak systems. This will usually be RD1, 2 or 3 but in low twos or low 3s we can start with F2 or F3 respectively. In a Neutral OR count (hovering 0) we can start with System 40N or OTB4L. so does it take a -8 count to make use use one of the streak systems? 3 does the 40 advanced replace the need for the 40N part of the system? 4 do we really need to change systems I thought our sap chart would keep us out of trouble?
