Where Buddy Distances updated too?

Yup, without testing..should be how it works

However thats the old/default distance for most 5km pokemon. They was 3km before, meaning 1.5km during this event.

Allot of 2km egg pokemon only require 1km walking per candy however. Minus afew of them who require more.

(starters also require 3km even though they hatch from 2km eggs)

The question is, has some of these new 2km pokemon had their walking distance scaled down also to 1km? some...if any at all.
(Which would mean just 0.5km during the event)

1km per machop candy seems alittle too easy to me, but maybe some like ekans and sandshrew have been reduced while others remain at the default 3km, who knows

Ah, got it now. I agree with you, like Squirtle (From 2km eggs but 3km buddy distance).
