Nickel Metal Hydride (NiMH) Handbook and Application Manual - Ver 02.01 of 2020

Here is a download link of latest available: (NiMH) Handbook and Application Manual, by Energizer Battery Manufacturing Inc.

Within this document, Page 10, there is an interesting reference: Voltage Cutoff at High Rates
I am currently have hard times to decode this information.

The test engineer, he should re adjust at discharge test, the termination voltage in to a lower level.
This be 75% lower from mid-point voltage under High Rates discharge.
 
Unfortunately for us:
1) Energizer engineers they skipped to mention of how us will determine this mid-point voltage?
2) Also this 75% calculation, this does not seem to compute right.
If we perform a reverse calculation,  0.9V Cut off plus 75%, we get 1.575V as NiMH staring voltage under a slow rate discharge test.

This unclear supply of technical information, it makes me wonder, if this is a real technical document, or just text this serving mostly marketing purposes?

Energizer Battery Manufacturing Inc., they do have at their hands, some short of advanced charging / discharging test system.
This test system it can even determine, battery internal resistance, by the use of pulse loading.

In conclusion, I do not find at this Handbook and Application Manual, the offering of necessary details that we regular mortals can use.

Its a known fact, that actual technical knowledge this is supper expensive in our times, so this to be offered for free.
But I thought that Energizer, this makes money primarily from battery product sales, they do not have any good reason, them to hide battery discharge testing details.
