Single post in Your Guide to 90%+ Breeding Pairs

Haha, yes, I understand not to hedge my bets on just two Pokemon, this isn't my first rodeo with breeding pairs XD And yes, as I said I know I'm the OT of the Beldum so of course I didn't try and test the pair myself. This was just one of multiple pairs (3 beldum and 4 different ditto) The reason I'm confused is as far as I can tell these are two different OTs, and this Beldum also paired at 63%, 64%, and 66% with 3 other different ditto So why is this one so far off the mark? Edit: Also me being a derp and forgetting that I may have accidentally tested this pair myself previously.
