Yup!
Or make the coil a bit longer than needed, then when done tweaking...
Make a "completed" one once all the fine tuning is done.

But in my limited experience, there is still a lot of manual tweaking

I'm not an amp builder, but my EE classes included load lines for
tubes so that we could compute their dynamic output resistance, so
this advice seems spot on to me.
Our class of '64 was the last to have to buy a complete set of RCA
tube manuals, which I still have (and would gladly sell). I also
bought the red transmitting tube manual.
