How Steal An Egg income is calculated

Every pet has a base income and a hidden base weight. A heavier pet earns more, but not in a straight line:

Up to 125× its base weight: base income × (weight ÷ base weight)^37/60 × mutation.
From 125× upward it slows down: base income × (weight ÷ base weight)^2/5 × 125^13/60 × mutation.

Both parts meet at 125×, so the curve has no jump. Example: a Kitsune at 10× its base weight (2,600 kg) earns $7.45B/s, 4.14× its base. Formula from the wiki's Mutations page.

What a bigger pet earns

Multiply a pet's base income by these numbers for its size. This is the same for every pet.

Weight vs base	Income multiplier
1× (base size)	×1.00
2×	×1.53
5×	×2.70
10×	×4.14
25×	×7.28
50×	×11.2
125× (slow-down starts)	×19.6
250×	×25.9
500×	×34.2
1000×	×45.1
