Thanks for all the tests + sharing this filter with the community, just got mine in the mail, going to install now!

Good idea, next time I mess around with the filter I'll run it empty and see. There's not a lot of surface area blocked so I expect it to just be a minor drop. The coarse filter may let a lot of light through but it's still a meaningful restriction to airflow.
