Yeah, it's not a lot of bang-for-the-buck on a onesy-twosy basis.
But, over the course of a year, with thousands of cats, it could add up. It might make the difference between being profitable or not. It might let you undercut others but just enough to get a few more sales.
The "game", as I see it, is two-fold.
First, and foremost, the goal of the breeding process is to device processes and procedures which reduce, if not eliminate, randomness from your results. (It's the fact that this is quite possible, along with proper management of the starter lotteries, which bring breedables out of "lottery land" and into compliance with the LL ToS.)
Next, is the careful management of resources, such as time, money, prim-space, to minimize your expenses and maximize enjoyment and, hopefully, for many, profit (or, at least, for the vast majority of us, minimize losses).
Calenders suck. Even though we all have one which will pop up appointment reminders, how many of us actually USE them?
On the other hand .. seeing that week-old kitten on Pet Food Recovery (or sick in its blanket) might actually aid you in remembering you actually have important plans for her.
It's all in how you look at it
Talking about the actual processes is good.
But let's not forget that one of the biggest problems we all have is ourselves! We don't just want procedures which help get better cats. We also need some which help us overcome our own foibles and failings.
