Using the ground state of the hydrogen atom
Psi 1,0,0 = sqrt([pi]*a3) * e-r/a

I get <r> the expected radius as <r> = 3a/2 where a = Bohr radius.

Anybody happen to know if this correct?

It would have been cooler if the Bohr radius in physical constants were <r> and the scale factor were in Psi 1,0,0.

Yes, your value is correct.
