Cutting down and opening up
As long as I'm making changes, I'm going to try cutting back to a 3-page treatment every two weeks, and let myself pick from any of my loglines, ever (and choose from any 3-page when writing a 10-page, etc.).
The first change will, I think, do a lot to improve the quality of my 3-pagers without cutting back on actual productivity too much (half as many 3-pages, sure, but same amount of everything else (for now)). And then the second change will make up for the lesser selection that cutting back will cause.
Whatever, I'm just kind of feeling around. We'll see what works.
