Ranking 'best systems'

Hi Matthew

I am wondering what the criteria are for getting in the list of best futures systems and how the list is made up:

My system Safe Capital has higher profit% then any other system in the list, but yet it shows up only somewhere in the middle. I was wonder what the filter and sort order is to appear in this list. Thanks for the feedback.
