The prop really is not much different to a Prony brake ...
so the figures ought to be fine ..... but ... as a generalisation ... depending on the engine and prop combination, conceivably they might not cover the range of power settings you can achieve and, potentially, you could over boost the thing trying to make RPM for the cruise prop installation .. or overspeed for the climb.
This is why the certification addresses the range of props approved for installation ....
I guess for the flea power engine indicated there won't be much of a problem here .... presuming that the aircraft is not used much for other than circuit and similar local work.
My own experience of climb and cruise props installed in lieu of the "standard" unit is that they are very much a two-edged sword .... you never get a free lunch ...
