in reply to Powerball Frequency Analyzer

I took a look at chromatic's program from 2000. Great code to start from.

I updated the code to process the current www.powerball.com winnums-text.txt file, after you've saved it to disk and stripped the one header line, and deleted draws before 08/31/2005 (the last modification to the game).
Also, my mod'd version of your program -
1) analyzes powerball and white balls separately,
2) determines a list of "cold" low count balls, "mid" middle count balls, and "hot" high count balls, and
3) does not report the Power Pick (or multiplier).

I will continue to tweek it until it is acceptable to me, and I'll probably post it to a new page here on Perl Monks with the same attribution currently in the code when my verison is to the point that it can --
1) use GET to access the current file, and
2) ignore the first header line while processing(will have to change the foreach to a while, I think... I know I've done this before on another Perl project).

Anyway, here's my copy after working for a few mins updating a couple of things and changing the reported numbers slightly ...

My current listing follows (I hope) --
