Given the size of the work we do, I think that a slow drop through the strain point, like yours, is just as effective as a strain soak.

shut off

I've had a very good track record when it comes to breakage (a few incompatibility crazes and beads that were already doomed going in), but to be extra safe, should I be focusing more on soaking at the exact strain point with my schedule?

Great info, btw!
