I relate. There is no universally valid way to measure understandability and any note can be subdivided so many different ways.

> Each note should contain a single idea and should be understandable when reading in isolation.

It's really a guiding principle. Unlike index cards in filing drawers, markdown with wikilinks allows for infinitely long notes and a low cost for context switching. you can choose whatever balance of note size/quantity you want.

In my markdown-based second brain built originally in Obsidian and now in Dendron, I have around 350 notes with what is probably a Poisson distribution of sizes. The important thing is that jumping from note to note costs very little.

further, if a note warrants splitting, now you can do it as fast as you can think it. The founder of Dendron aptly describes this as a part of the amoeba pattern: https://dendron.so/notes/e780000d-c784-4945-8e42-35218a3ecf1...
