Historical performance data for climb typically comes with a climb speed information. This climb speed hardly ever is constant.
Climb speed will never be constant with altitude. Any pilot or first year aeronautical science students knows this....

Climb rate without speed is useless information. All aircraft performance occurs at a specific point on Power required curve and is fixed by the design of the aircraft.

If speed is held constant, the aircraft is not maintaining the best performance point on the Pr curve.
