Welcome I see your query was already answered.

I think it's something simple: everyone starts at 100 and this number is multiplied by any given decimal at the end of those compatibility reference points (PhitDoctor lives too far away [.9]). The result (90) is multiplied by the next decimal of your choosing (PhitDoctor also likes sports,movies, and kronenberg [1.1]). Then, that result (99.9) is multiplied by the next value and so on.

So, if I'm looking at an woman who lives too far away [.9], is out of my desired age range [.85], is into some of the same stuff [1.05], doesn't have the education I'm looking for [.9], we're not looking for the same thing in a relationship [.7], and I haven't filled out my bio description [.85]. The final value would be:
100 X .9 X .85 X 1.05 X .9 X .7 X .85.
90-> 76.5-> 79.885 ->71.8665-> 61.3something = what you see 61.0]

I, uh... I like mafs.

I don't know what basis for assigning value to each compatibility data point they use. Seems like some arbitrary relativity scale.

I also like value system theory.

I just thought it was how you matched with the answers to original questions with others?

I have been here a couple of months and my first college degree was in mathematics and my observation is that the progression to each level here is an application of the exponential function.
