I"ve been playing 428 all year, it has dropped 1 time this year, as 482 on April 1st, 2010.

472 has dropped, like 5 times this year, and at least 4 times in the same form, 472.

Is there a workout I can do, that will let me know, if 428 is coming soon?

I just do the one up from each number and the one down, or, if 427 drops, I start playing, 428.

Thanx in advance.
