Buffering, Intentional vs Unintentional model

I’ve found a few other great resources for different topics/thoughts I have written down. I’ve been looking in the study vaults and found some really good ones for the past month which I’m considering doing. I find the topics buffering, and intentional/unintentional models comping up in my thought downloads.

Where can I find solid resources on buffering in the study vault?

Also same question but for intentional vs unintentional model?
