The only thing I don't understand is the naming of 'checkpoint_smoothing'.
Can users imagine the unit of 'smoothing' is a fraction?
You explain the paremeter with the word 'fraction'.
Why don't you simply name it 'checkpoint_fraction' ?

I chose checkpoint_smoothing because it tells you what the parameter is
for. If you want more smoothing, tune it up, and if you want less, tune
it down. checkpoint_fraction makes you wonder what you can do with it
and why you would change it.
Sorry if I'm missing discussions abount the naming.
No, I chose _smoothing on my own. People didn't like
checkpoint_write_percent either (including).
