There is sorta a pattern,
00 00 00 00 42 00 00 00 00 00 00 00 8C 15 0D 02 E0 FF
<02 - 03> 00 00 00 <random> <75-79> 28 02 <random> C1 27 02 05 18 07 02 00 00
I am sure with more Pokemon pal park'd we can maybe find that <75-79> can range to even 74, 73, 80, or 81. Maybe the second random number is always even.
