Somewhere between writing and planning/researching. I'm coming up on writing some scenes I've been excited about, and I know the general shape of things in the outline, but there's a still a few details I'll need to research for once I start getting words down on paper. Just waiting for an opportunity when I've got a bit of downtime to focus in on writing.

Usual duration varies a lot depending on what else is going on in life, but I aim for minimum two hours when I'm able. Doesn't always work out that way though!
