So (newbie here) I've seen some versions of nanoVNA that capture 1000 data
points rather than 101. What are the consequences of the larger number of
points?
Thanks,

Stan: All very good comments. I would like to expand on your statement
regarding calibration interpolation. How "nice" a job it does depends
somewhat on the quality of the instrument and setup (cables, adapters,
etc.); If the setup is well-matched (to 50¦¸) and low loss, and does not
have any resonances, the software will be able to interpolate well. I do
not believe that it will extrapolate outside of a calibrated range,
however.
But you need to keep in mind the sweep width and number of discrete
measurement points so that you do not miss an important feature by stepping
past it; this would be an issue with a narrowband filter or high-Q antenna
such as a tuned loop..
