Disregard the bit about it being inexact.

There's two ways to deal with multiple discounts - one might say the right way and the wrong way, but lets stick with multiplicative and additive.

If we take the descriptions: Nursery "Cutting-edge advances in Monster-Nursology [sic] have culminated in this brand new structure upgrade! The Enhanced Nursery Features a warmer lamp, gnarlier toadstools, and shorter incubation times... 25% shorter that is!"

Skin "- 10% speed up incubation in Nursery"

One might assume it is multiplicative: Take the original value, and subtract 25%. Now take that value, and subtract 10%. As a mathematical notation: X * (1 - 0.25) * (1 - 0.1) In this method, a Shrubb would take: Standard: 8 hours (480 minutes) Enhanced: 6 hours (360 minutes) Enhanced+Skin: 5 hours, 24 minutes (324 minutes)

In actuality, it appears to be additive: Take the percentage speed-ups, and add them together. Take the original value, and subtract this sum of percentages. As a mathematical notation: X * (1 - 0.25 - 0.1) In this method, a Shrubb would take: Enhanced+Skin: 5 hours, 12 minutes (312 minutes)

This latter number appears to be the case (though shown as 5 hours, 11 minutes, 59 seconds).

Anyway, doesn't affect the topic of this post, just wanted to add :)
