Clearly you can adjust the score values to tune it to something more
appropriate to you than 10%. And you might well want to change the set
of 'suspicious' characters. For instance, you might want to compare the
number of upper/lower case letters (in which case remember to use the
'D' flag for case sensitivity!). But hopefully it gives you the idea.
Thanks Martin.
Nice summary of how it works. That was just what I was after.
