Also, how closely does pitch speed correlate to actual flight speed, realizing that variables such as available thrust and airframe drag come into play.

Finally, P-Calc (brantuas) seems to deliver massive thrust numbers. How accurate is this program?
With a square prop your acceleration is probably pretty poor.

I would look at the whole power system and select the right battery voltage, motor, ESC & prop combo to reach the desired speed.
