Single post in Your Guide to 90%+ Breeding Pairs

I managed to get my Minior pair up to 93%! They're both level 50 and 77% base compatible! The Pokémon are very friendly toward each other. Matchup CheckerBase: 77% Happiness: +20% Total: 93% My question here is, I know there's a low level debuff, but is there a high level buff? If I get them to level 100 does that affect anything, or is leaving them at level 50 fine? Thanks again for this guide! :D
