Just thinking out loud about this note... and I have a couple of basic questions...

a) In your code:

    push @moving, $val;
    next if $#moving < ($MOVES / 2);
    shift @moving if @moving >= $MOVES;

Can you give me a quick explanation of what the middle line is doing? I'm not familiar with the '$#' construct.

b) You also have the following in your code:

my @rounds = $EXTRA ? ( 44, 90, 100, 110, 120 ) : ( 44, 90, 120 );

[download]

It would certainly simplify my job if I knew and could specify these values (that is, 44, 90 and 120)... but in many cases, I don't KNOW those values. Is there a means to simply determine those values from the data... or should I simply create 10 'bins' for example (10, 20, 30... 110, 120) and gradually refine them until I get the 3 'real' values?

I hope these questions are clear enough. It's just that although I've been playing about with perl for 15 years or so, there are still a LOT of basic constructs and things that I don't know about...!

Thanks again
