i'm more surprised they actually are keeping the Beta Credit in 2020! I thought they were discontinuing it once 2019 is over. I need to look more into this.
I usually hit the ~100K views ($200 tier).
With this new plan, many would probably be a hair away from the $300 credit, since there is no longer a $200 tier anymore : P This is fine i guess. The trade off of having this program continue is worth it.
Protip: You get significantly much more views per month if you split your uploads into many smaller parts as opposed to fewer but longer episodes. If you don't care for Beta Credits then upload however you please : P
It's automatic once you successfully connect your Patreon to your webcomic 
Every month you can find a notice with a list of all legible creators with how much everyone is getting too ( good for insight
)
