Test array generation...

I made a 'array sort' for some testing, but wonder if it can be done better [in ruby 1.8.5] or if anyone has better to share...

as this is I get 180 edges 'grouped' in 0.99999

which is fast enough for my needs, but I wondered if there are better ways.

Sorry, but can you do a short explanation of what you are doing? There's some cryptic variable names there, and some funky indentation. :s

TT

added commenting to the original code block to try and explain things better, I can't get the formatting to hold...

but this is better.
