Hm, I got this as a valid method 1 PID (since Legendary birds are Method 1). I also was under the impression that Zapdos had to be frame 1 or frame 6, since that is how it would be generated...
Got that impression from here.
I see alot of "Method 1/J/K"... how synonymous are the three methods?
And yes, I did use pandora through a lot of trial and error... wasn't even deliberately looking for a shiny, just a modest with good stats on frame 1.
