In other words, MatchMatrix is a hoax.
Here is the full report, written by Drs. Houran and Lange.
I remember I tested MatchMatrix during last July 2009 and I suspect "Friends" and "Lovers" outputs are combinations of a "modified" Biorhythms comparison! The first thing I noticed is when you maintain a fixed Birth Date in an input and slowly varies the other input, the outputs resembles sinusoidal functions.
