Yes, they did. As for Spinda, it's not like they actually create each and every single one of Spinda's spot patterns by hand; the very thought of that is ludicrous. They have a base model for Spinda with no spots and have the computer run an algorithm that adds spots to it based on its PV. That's what they've done for every game in the past and I see no reason to think it won't hold.
