This is a 369 theory good for pick 3 however it may or may not be good if a double drops but a quick little workout

when you haven't had time to study remember the 0 may be a 5 so keep that in mind. 

I think I forgot the formula for doubles I'll have to go back through my notes 

many people have visited tesla's theory I have studied it and re-studied it and find it 

fascinating always something new to learn
