Some strategies have a lot of wiggle room.

Imagine for example there is a massive secular trend happening that is leading to the growth of a seedling product of yours that has a sustainable revenue model, and that seedling is inherently very sticky.

In that case, the LTV of customers is going to be huge; you can give away a lot of freebies to get them onto it before they go to a competitor and get stuck there.

You don't have to worry about getting the math precisely right, because the size of the long-term aggregate LTV is so high that there's a ton of wiggle room.

A robust strategy!
