Physically, the best rate of climb is the point on the power curve where the greatest difference between thrust horsepower required and thrust Horsepower available exist.
where thrust horsepower is equal to Thrust * Velocity (TAS) So as TAS increases and likewise CAS or IAS will have to increase in order to keep the relationship.
T*Vreq-T*Vavail a constant.
