Note that in all these stated cases, the speeds/power settings are not certification nor performance limits, and hence can be set by the specific operator.
IE; different strokes for different folks.
Having said this, some airlines try to have a 'standardized' check list for all fleets.
This is seldom satisfactory, and can lead to mistakes in operation.
The best idea I noticed was at what is now the largest airline in SE Asia, years ago.
They had ten B707's...from four previous operators.
ALL of their operations/performance manuals said 'Boeing' on the front cover, and when I asked the fleet manager why, his reply was...'Boeing manufactured the aeroplane, supplied the operating data, so we use the best information available.'
Seems entirely reasonable to me.
However, there are airlines today that are still trying to reinvent the wheel...
