This is a game, not a measurement. Eight answers each carry a number somebody chose, the numbers are added to a starting 100 and the total is clipped to a range from 0 to 100 percent. Nothing here predicts anything about a real person, and no psychology went into any of it.
The numbers at a glance
Held fixed: How did that text end? With a full stop, Did an ex come up? Once, briefly, How heavy did it get? Small talk throughout, Who paid? Split down the middle, Who did the talking? Roughly even, How did you say goodbye? A hug, How was the laughing? Polite laughing.
score = 100 + eight chosen numbers, clipped to 0…100
1StepAnswer the eight questions honestly, which is the only hard part.
2StepEach answer adds or subtracts a number somebody picked out of thin air.
3StepThe total starts at 100 and gets clipped to the 0 to 100 range.

What this number means
There is no science on this page and that is the whole design. Each of the eight answers carries a number, the numbers are added to a starting score of 100, and anything above 100 or below 0 is clipped back to the edge. Five combinations shift the total a little further: three dots plus a long wait costs eight, an ex brought up alongside tears costs ten, real laughing with an even conversation and a hug pays ten. Where do the numbers come from? Somebody picked them. That is the honest answer, and it is worth stating plainly because a percentage sign is very good at looking like evidence. Assigning numbers to ordered answers and then adding them up produces something that behaves like a measurement without being one: the ranking may be defensible, the distances between the steps are invention. So the sixty-five point penalty for a repeatedly mentioned ex is not a finding about dating. It is a joke about how much attention that detail gets at one in the morning. The calculator makes no claim about the other person, none about you, and none about what happens next. It exists because the night after a first date is spent re-reading one text message, and a silly number is a cheaper way through that hour than another read.
Every number here was chosen, not measured
No study says a full stop is worth minus fifteen points. The values are a convention carried over from the calculator this page replaces, and they are shown in full in the table above so nobody has to guess.
Points on ordered answers are not a measurement
Ordered categories support a ranking but not a distance, so the gap between two answers has no defined size. Adding such numbers gives something that looks quantitative and is not.
It says nothing about either person
This page makes no psychological claim, offers no read on the other person and diagnoses nothing about you. It is a scoring sheet for a joke.
The clipping hides a lot
A very good evening scores far above 100 and a very bad one far below zero, and both get cut back to the edge. Two results of 100 percent can sit a long way apart.
Commonly misread
It said 39 percent, so the odds really are about one in three.
The number is a total of made-up points wearing a percent sign. It is not a probability of anything.
The ex penalty must be based on relationship research.
It is not based on anything. Every value here was chosen by whoever built the original calculator, which is why they are printed openly rather than hidden in the code.
A hundred percent means it could not have gone better.
The total is clipped at 100, so many quite different evenings land there. The score stops distinguishing once it hits the ceiling.

Questions
Is this based on any research?
No, and it does not pretend to be. Every point value was chosen by a person building a joke, and the page shows them all rather than hiding them.
Why does it output a percentage then?
Because the original calculator did, and because a bounded score reads more easily than a raw point total. Treat the percent sign as decoration, not as a probability.
Why are there only eight questions when the old version had ten?
This site allows a calculator eight inputs at most. The two dropped questions were the ones that moved this particular result least, and one of them moved it not at all.
Does the result say anything about my date?
Nothing whatsoever. The page makes no claim about the other person, no claim about you and no prediction about what happens next.
