What is the difference between low-grain and fine-grain? Context: Granularity in Computer Science, Slate UI Documentation

[8Zerocool8 (Voidbit)]

I am currently going through the Slate UI documentation and came across the term low-grain.

The same documentation page I am referring to, also uses the term fine-grain, which I understand. But what would then be the difference between fine-grained and low-grained? Could someone who understands the difference here please explain?

My assumption so far: Low-grained probably means coarse-grained in this context, as when something is coarse-grained it has a low number of grains (i.e. sub-components, child elements, etc.)

My assumption is correct.

• When UI structure is changing, prefer polling to notification. (When notification is necessary, prefer low-grain notifications to fine-grain notifications.)

The statements quoted above make it clearer and can also be found on the Documentation page I referred to.
