I removed the template because this is a suggestion not an issue, but if i'm wrong, tell me and i will fix it.

The Pam's "Apple Tree" and the "Oak Tree" have the same chance and amount of apple drop and this is not really correctly as the Pam's Apple Tree is made specifically to grow apples.
I recommend doubling the Pam's Apple Tree drops: 4 Apples, 40% chance.
