The counterweight has been, after using it for a bunch of projects, I have internalized that it will very, very quickly get me to maybe 60% and then I'll have to take it the rest of the way mostly by myself (or handholding it tightly for the remaining 40% at a much slower pace).

In other words, the initial implementation is practically already there, already done. So there's no rush left in generating it - it's only worth bothering if I'm prepared to see it through to 100%.

When it is worth pushing through to 100%, it's pretty great for getting the inertia going though.
