Prophecy of love compatibility

I´m going to explain one simple Japanese prophecy of love compatibility that I learned from "Proposal Daisakusen" (3.episode if you're interested). I was really interested in how they calculated it, but I understood it only after learning basic Japanese myself. So I thought maybe there are more people interested in how it's done. I hope the way I have explained it is easy to understand.

Love compatibility between Rei and Kenzo. YAY 94%!!!

It´s much easier with Japanese names of course, but once you know katakana, then it isn´t so difficult. 
1) First of all you have to convert your names into kana (doesn´t matter if it´s hiragana or katagana), which basically is Japanese syllabic alphabet. As you can see on the previous picture: Yoshida Rei is written in hiragana as よしだ・れい. Foreign names can be converted into katakana, for example Karin Kask would be カッスク・ カリン (Kassku Karin). While converting be sure that your name is converted correctly by it´s SOUND not by it´s look. For example Ryan Reynolds would be ライアン・レイノルズ (Raian Reinoruzu) and not リャン (it's read as Ryan, but it sounds like Nyan with an R).
Remark that in Japanese the family name comes before surname!

2) After converting your and your beloved one´s names, write them down, putting the name of a woman before the man´s name. As you can see on the picture Rei´s name is written before Ken´s. Not sure why, but I've only seen it this way round.

3) The most difficult part. Mark the syllables with numbers. To make it simpler to understand,  I added the kana table. To mark the syllables with numbers:
All of the syllables with A = nr 1.
All of the syllables with I = nr 2.
All of the syllables with U = nr 3.
All of the syllables with E = nr 4.
All of the syllables with O = nr 5.
As you can see letter N is the only one alone, that´s why Letter N = nr 0.

For this point you should have two rows already. First is your names in kana and the second is the first row of numbers that are marking your syllables. Look at the picture of Rei´s and Kenzo´s compatibility: Under Rei´s name you can see the numbers 521 42 as Yo(5)Shi(2)Da(1) Re(4)i(2).

4) From now on it´s only about maths.
You have to add together the first and second number. Then add together the second and third number ETC. till all of the numbers have been added together with their neighbours. So every number gets added together twice (except the first and last number, because they have only one neighbour). When the sum of the numbers is 10, then only 0 is written on the next row. For example on the second row of the pyramid on the left side there´s 7 and 3, which make 10 when they are added together,　but instead of 10  - 0 is written on the third row.  When the sum of the numbers is bigger than 10, then only the second number is written down on the next row. For example at the picture on the second row of the pyramid on the left side next to 7 and 3 there are 5 and 6. 5 and 6 normally added together make 11, but instead of 11 only 1 is written on the next row. This way every next row is smaller by 1 number than the last row was.

5) Add the numbers together (row by row) until there is only TWO numbers on a row. Those two numbers are the per cent of your compatibility.

Compatibility between Oku Eri and Tada Tetsuya

Now you know the per cent of your compatibility. Once you´ve understood how it´s calculated, it´s really simple (and addictive) to calculate it yourself. When the per cent is low, then don´t give up. It´s just another prophecy and sometimes it's better to have lower compatibility because this way you both will work harder to maintain the relationship. :)
