Mempool graph ---> https://jochen-hoenicke.de/queue/#24h

I've been doing quite a bit of research on the Mempool.. still dont feel like I have the best understanding of it. From what I understand the mempool will tell you how many transactions, unconfirmed and pending transactions.

On the graph that says unconfirmed now there's roughly 1800 unconfirmed transactions @ 5 sat/b, how do I know if that a lot or not many? How do I gauge what sat/b fee I'd want to pay?

On the graph that says pending. At 10 sat/b there is roughly 2.3 BTC pending, how do I gauge if this is a lot or not?

The last graph is mempool size in KB. At 20 sat/b there is roughly 1,700kb, once again how do I know if this a a lot?


I feel like I can read the graph it just don't mean much to me at this point. If someone could explain or direct me to a link that could explain I'd appreciate it.
