>>20582548Long story short, all values are determined the moment you get the steps required for an egg to appear on the daycare, after one egg has appeared, they follow set patterns for the stats.
Lenghty explanation:
Random IV values are RNG'd and follow a preset pattern from a huge value table; gender and shiny IDs are also determined by another randomized list. Each time an egg is created, they select a combination from that table for the first one, and they'll follow the next combination from that table, until you alter something on the breeding, like using an everstone/destiny knot/change egg groups/ditto/etc.
Using Destiny Knot, though, changes the table settings to just RNG 1-3(rarely, most times it's 2) random individual values, then they RNG the inherited IV combinations from parents from another set table of IV spreads, however. Then, follow rest of the procedures the same way as normal eggs.
>>20582660Basic RNGing actually, which is the "Time machine" method you described.
Check the IV's of the pokemon in any of those two options, see if you like'em, if not, discard themrelease them, and follow the next one from said tables, until you get whatever you want.
