Don't wait. Go drive normally 'till it warms up a bit, then do some full throttle pulls in 2nd gear from 2K RPM- 4K RPM, then coast, and do again five or six times. That's it. The first 20 miles are critical, and if you wait too long, the rings won't seat and you'll need to re-ring and re-hone.
Flooring it early on will force the rings against the cylinder walls, and the cross hatch honing will "shape" the rings to seal against the cylinder wall. If you drive gently, this won't happen, and the honing will be worn off without the rings properly seating.
