If "internal compatibility" between #2_try and #3_try is equal or slightly higher than "internal compatibility" between #1_try and #2_try, then #3_try is the one to be added to database.
FERNANDO ARDENGHI -- short bio Fernando Ardenghi (40+, electronic engineer UTN 1995) has 15+ years experience in Information Technology and 10+ years experience in the Online Dating Industry.
Fernando Ardenghi is the inventor of LIFEPROJECT METHOD, a compatibility matching engine by strict personality similarity using the normative 16PF5 test or similar.



Personality matching method with personality tests like 16PF5 and high precision advanced math equations.
World Wide, there are 5,000 online dating sites, but no one is using the 16PF5 or similar to assess personality of its members!
My name is Fernando Ardenghi and I am a 40+ years old Argentinean electronic engineer with several post graduated courses.
Women not taking contraceptive pills should take the test at least 3 times: 7 days before, in their real periods and 7 days after, and also synchronize with biorhythms (for future Research purposes).
Women taking contraceptive pills should take the test at least 3 times: 7 days before, in their false periods and 7 days after, and also synchronize with biorhythms (for future Research purposes).
Both men and women should say if they are under other hormonal treatment.
For each persons "internal compatibility" will be calculated between #1_try and #2_try, and between #2_try and #3_try.
I have invented a new on line dating / social networking method named LIFEPROJECT (startup, ready to launch). showing the newest & freshest Research in Theories of Romantic Relationships Development clearly show: compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.
I plan to acquire the license of the 16PF5 normative personality test, available in different languages to assess personality of daters, or hire a Psychologist to develop a proprietary test with exactly the same traits of the 16PF5, to construct a copycat version of the 16PF5 (one per language and norm), but improving it using Item Response Theory / Rasch Scaling (the Gold Standard for Modern Test Theory) with different questionnaires for men and women and all the questions rearranged in a Rasch hierarchy.
It will be used as the personality test for a new dating site intended for serious daters, offering solely strict personality* similarity*.*personality: measured with the 16PF5 or similar normative test.*similarity: calculated using the high precision quantized pattern comparison method I had invented, named LIFEPROJECT method (part of pattern recognition by cross-correlation).
Men should take the test at least 3 times and also synchronize with biorhythms (for future Research purposes).
