Please do!

As I said in the first message, I don't know enough to figure this out
single-handed, but I'm interested in learning. I'd be happy to undertake
exploration, do grunt work, and maintain momentum, but I'd need a bit of
direction from people who know where to look.

Would the profiling results I linked to in my first message contain any
useful clues?
