Shall we call this the amazing 55 / 00 which as well all know 00 is the same thing ........lets look 

When you get a 55/00 pair then look for these numbers as well . .............. its amazing !

55- 7 , 12, 17, 22, 27, 32, 37, 42, 47, 52, 57, 62, 67, 72, 77, 82, 87, 92, 97

I call this next little section where does it end b/c most of the time it ends with one of these 

102, 107, 112, 117, 122, 127,132,137,142,<<<< etc all your doing is adding 5 to the last digit to get to the next .

the marriage of two numbers like 273 is just putting pairs together to give you both pairs that show up above and that will give you a base number soon. 

take the number 973 your using 97 pair and 37 pair which last time it fell produced a base pair ( a base pair is a pair that has equated to over 100 and can no longer be called a pair ) so it produced 674 a marriage of the 67 and 47 pair from above .
