There seems to be two schools of thought that I can discern. The first one are the devotees of wheeling as started by Dimitrov. The second are the devotees of repeat cycles of number groupings using the algorithm of de Moivre . The main proponent is Ion Saliu. Looking around the sites devoted to lotteries it would appear that the wheelers are in the majority, no doubt influenced by the preponderence of this school of thought on the net. I wonder if people actually use rational judgement as to which school of thought they decide to embrace or do they just follow the flow.
