I think the disconnect here is that you can't only retype the solutions. You have to already sort-of know what's going on and you have to also care to understand the gaps.

So transcription can definitely be helpful when part of a broader, intentional process, while also being insufficient to do much on its own.

And the next logical question to ask is whether there's a better form of intentional behavior that might be more effective.
