Not sure on this but I think that the Oval Charm increases it by 30% so it would be 99.3%. Like I said. not completely sure on this.

Freshly imported from Ninja.

>> Increases the chances of a Pokémon producing an egg.

>Not good enough, huh? :P

God, dis was difficult. This is a valid answer so far, and I cannot find anything anywhere else saying otherwise.

>---
The chances are changed every 256 steps.

>After looking into the code with some tools of mine(calculation tools, editing tools, viewing tools, coding tools, etc.) (legality questionable?), I found some stuff on the Oval Charm. So, I ran calcs, and got a 10% increase the first time. After retrying it, it went to 11.25% increase. Tried it again. 5.75% increase, and other various numbers.
