I know a perfect pair has the best odds, but since I'm not going to scour users' boxes to find a matching gender one for over a 100 events; what would be the next best odds? I've been breeding Autumn Kadabra + Kadabra for around a month now, with no luck.

Which has the best overall rate (# of events/week; considering both the breeding rate and event rate) - event + counterpart, or event + ditto?

Event + counterpart does have a better breeding rate, "get along very well", while event + ditto has "get along". But which has the best event rate?

Are the eggs 50:50 for both, and if it rolls a ditto, you don't get an egg? Or for event + ditto, is it 100:0, therefore getting less total eggs (due to the lower breeding rate), but the same percentage of events as a perfect pair?

If your goal is maximum events per week, you’re better off using event + counterpart rather than event + ditto. Even if both have about the same event probability per egg, the higher egg production rate from “get along very well” will give you more total events over time. The only reason to use Ditto would be if you don’t have a compatible counterpart or you’re trying to pass down something that only Ditto can help with.

After quite a bit of searching, I can conclude that breeding an Event with Ditto is the next best alternative to a perfect pair.

There was quite a bit of conflicting information, but:

Quote from CatLady"Riako did say that any pair with Ditto has an almost 40% lower egg drop than the Perfect Pair equivalent."

Quote from DragonSumedh"He [Riako] said the chance of getting event eggs from Ditto and two event pairs were the same."


Users said that event + non-event was better than event + Ditto. This is wrong.
Users also said that single-gender + opposite-gender;same-egg-group was worse than single-gender + Ditto, as only half are the eggs you want. This is correct, and similarly applies to events as well.

The difference in event rate is more significant than the difference in breeding rate.

Assuming the 40% lower rate for Ditto applies to all "two seem to get along" pairs, we could estimate "two seem to get along very well" pairs to have around a 20% lower rate [than a perfect pair].

Perfect pair of 2 events: relative breeding rate of 1, each parent contributes 50:50, let's say 5% event rate
(5+5)/2 *1 gives a relative event factor of 5
Event+counterpart (get along very well): relative breeding rate of 0.8, each parent contributes 50:50
(5+0)/2 *0.8 gives a relative event factor of 2
Event+non-counterpart (get along): relative breeding rate of 0.6, each parent contributes 50:50
(5+0)/2 *0.6 gives a relative event factor of 1.5
Event+ditto (get along): relative breeding rate of 0.6, ditto doesn't contribute
(5)/1 *0.6 gives a relative event factor of 3

Therefore, in the same amount of time, an event+Ditto pair would produce 50% more event eggs than an event+counterpart pair, but 40% less than a perfect pair.
