Wait what?  My compat with Proper is 89.6%, that's like only 2% off from my sister's.  O.o  Heh, correlation measure only taking relashionship but not absolute weights into account.

lolwat

i thought wee had completely different tastes

That's an artefact of how the correlation is calculated.  Correlation only takes into consideration the strength of the relashionship, and not really the actual weights.

For example
A   B
4   8
3   6
5   10
Should give perfect 1.0 correlation.  If you plot them, they make out a perfect straight line.

Which is pretty much matches our case here.  Even though you rate everything higher than you, wee show a positive "relationship" because stuff that you rate comparatively higher (compared to your other stuff), I also rate comparatively higher (compared to my other stuff).  That's largely because some stuff are just better than others, like Kanon (which wee both rated pretty high) is just better than Traning with Hinako (which wee both rated pretty low).

So it's more the quality of the shows rather than our tastes.  What would be a much better measure of our true tastes would be to calculate the correlation based on our score deviation from the mean for that show rather than raw scores, but that will probably never happen.



And another thing I find extremely dumb is that they convert the -1 to 1 correlation scale to the 0-100% scale.  This is dumb because a moderately weak 0.5 correlation becomes a "strong" 75% compatibility.  And 0 = absolutely no relationship becomes 50% medium compatibility.  Herp herp herp.

juuust kidding

Lol, I never said K-on was bad.  Heartless said that.
