Interesting maths analysis. I'd certainly noticed that their ability to reliably rank inside a window of say, 80% and 95% was rather low, along with the ability to filter out deal-breakers. Frankly that remained a manual process, no matter how much data people had supplied, I never could do that reliably from the numbers alone. As a liberal Christian, I end up with quite a bit of filtering of filtering out of people with very great differences in either religion or politics which the algorithms simply didn't pick up.

So anyway, some tweaking done. Let's see if it has any visible effect...
