I'm going to be trying for one map a month for most of this year, but that may change if I'm feeling particularly productive/if I use my energy for other things (for example, I've been drawing a lot more this year - I've considered putting some of my drawings up on here, but they're mostly just random drawings from a fantasy world I'm designing, so I'm not sure if all the people who watch me because of my allohistorical maps would approve).
I wish I could help you with the Teutonwank, but long timelines are really not my forte - I like making maps relatively soon after the PoD so that I can conceivably keep all the relevant history in my head.
