mtb it all depends what I see clear , for example I like to study HL and EO but mainly I’m a player that likes to chase front digits . You actually wait for the play to come to you , if you study the patterns you will see when they about to hit also when they about to flip . Also I’m a player that likes to play with the root sum
so knowing what front digit is coming you only messing with 100#s and knowing what root sum is hitting can drastically drop the numbers out those 100. It’s crazy how is so many ways to break a number down bro.
