I've updated the article slightly.
mingot yesterday told me that what the article stated as being Method 3 of creating a Pokemon worked incorrectly in the IVtoPID applet, and said that there was a fourth method that corresponded to the incorrect method in the applet.

applet, and the Ratings of Pokemon Base Stats
applet (now Version 2.0!)
. And also the IV to PID
