We're almost at 3lbs MVER, so what if the rH is over 90% ?

ASTM F-2170-11

9. Conditioning
9.1 Concrete floor slabs shall be at service temperature and the occupied air space above the floor slab shall be at service temperature and service relative humidity for at least 48 h before making relative humidity measurements in the concrete slab.

As you posted ^^^

You do not need a heater or a blower or a cooling system to provide the required conditions. Many facilities are within the stated parameters well before the HVAC system is functional.
