Pokewalker Pokemon seem to correspond to Method "Wondercard IVs" from RNG Reporter.
Starting Frame seems to be 0 and as it seems it is somehow possible to advance the frame, but not by too much as it seems but the Blogger could advance his frame +3 and as it seems it IS possible.
But so far, I can't tell anything more concrete, just came home.
About Seeds and Delays for Pokewalker:
Normal Delay: 19 (would be 2010)
Abuser choses 2029
Delay for 2029: 0
Normal Delay: 21 (would be 2010)
Delay for 2031: 0
In both cases the abuser made it to be the delay 0.
All Pokewalker abused Pokemon follow this pattern.
In one case he advances then his frame +1 in the other +3.
Currently reading how it is done.
The game is selected at 2:19:10, September 26, 2031.
The game start is done at 2:19:11, September 26, 2031.
How is THAT supposed to work and moreover what the frick that means?
Apparently there is a Excel Spread http://www1.ttcn.ne.jp/~era404/pokeuxo.csv
which contains useful Spreads for the Pokewalker which would work from 2000-2099, so indeed it seems to be pretty possible to abuse for kinda normal years too
