Existent processes appear complex and require frequent monitoring using
equipment unavailable to the normal woodturner.

Humidity gage and personal attention would do.

As Charlie, Arch, and many others have noted there are definite
differences in specific woods, even what region the wood comes from, etc.
Leading to the conclusion that even with an overall idea/plan/setup there
will have to be individual experience applied eventually. There were
specific gravity tables by type, etc. George has done much in that regard
with FPL but there's other sources to compare any differences in
conclusions. I usually prefer private enterprise to government for
conclusions unless there's an axe to grind.

You need to learn to evaluate the data, not disparage the source.
Otherwise, you'll have to luck into a reinvention of the wheel. Here's a
key piece of data for you - wood loses water ten or more times faster
through end grain than through face, and quarter grain is even slower.
That's why "an inch per year" is bunk when applied to a roughed turning.
That's all you need to know to evaluate some of the alleged rapid drying
methods. You're not doing boards, so only the principles apply, not the
specifics.
