Legality question with encounter database criteria tab...

[PLAFiles]

Hi. So, if I open the Encounter Database and then click on the Criteria tab and, for example, fill all IV's to 31 for all stats and click Search, does it force that encounter or does it show Pokemon actually encounter-able that could be possible in whatever game I have open? I only ask because while messing around on that tab and just seeing if all 31 results would come back for random Pokemon I was trying (specifically not from eggs), it was showing results for all 31 IV's in all stats like I set it to. For what it's worth, if it matters, this was for a Gen 3 game.

 

I just want to make sure it isn't forcing illegal results just because I set the Criteria to them.
