Unfortunately ROC is nonlinear with speed for a fixed altitude & wt.
ROC is proportional to excess power ie differecce between
what your engine is putting out at your power setting
and the power needed to overcome drag.  Its max at
about middle of the white arc speeds.
Remember also that book figures are one by
factory test pilots on new airplanes at gross wt at sea level
or corrected to sea level.
There is a way of performing an entire climb performance check
in a 1/2 hour flight with on board instruments.
Send mail if you wish to know how.
Good Flying.
