Man, I'm not too sure anymore
The last time I did a pseudo time test was in 2019, and I think the pages took about 8-12 hours at that time iirc.
My more recent comic was vertical format with more panels so I'm not sure how it factors in too well. I think those were taking like... 2 months-ish in 8 2 hour sessions per month to make 20-25 panels? 8x2 = 16 hours per episode, 20ish panels / 5 panels per page average = 4 pages. 16 hours / 4 "pages = 4 hours per "page"?
That sounds incorrect
I think my next project will be page format again so I'll have to do a proper timing later this year.
