I've updated the progress meter in the sidebar to be out of a more realistic 100,000 words, rather than the 56,000 or so I will likely need for my finished draft. My progress goes less quickly (and hence is a bit less inspiring for me to watch) with this method, but it's more likely to be an accurate measure.
Making slightly more progress here at the end of the week, but still disappointing overall. It's not writer's block, exactly - more like "dissertator's paralysis."
Also, the writing meter refers to total draft pages written; I'll need to add another meter for finished, or at least edited, pages. But - there's some progress there, yessiree.
