Small feeds on the lathe

:
I find I get the
best finish if the tip radius is larger than the feed rate ...

You mis-read my statement. I did not say "tip radius", I said "EDGE"
radius. Even a 'perfectly' sharp edge doesn't come to a perfect angle.
If it did, it wouldn't withstand any cutting forces. That tiny radius on
the edge has to be a small fraction of the cut depth, or skating will
occur.
