Anyone have a good reamer RPM chart?

I usually figure 2/3 of drilling RPM, but that's not always good enough.

For instance, .885" dia. reamer into steel, shallow process only 3/4"
stroke... I would normally run at 100RPM or so... But I'm guessing that is
ultra conservative for some of you.

The reamer is removing .010" material if it matters.

I thought that the conventional wisdom was half the speed and twice the
feed-per-rev.
