PSA: Cost-Efficient Egg Incubating
Using the ∞ Incubator (Orange) on 2km eggs is the most-efficient use of it!
I came to this realization after sticking a 10km egg into the ∞ incubator. I hope I can save other players from wasting the most efficient use of the 3-use incubators (Blue)!
Using the 3-use Incubators on 10km eggs nets you 30km total of walking use before they disappear! For comparison, using it on three 2km eggs would be gone after 6km!
