For the record, the accepted way to address endurance properly is to assume full load displacement, and economic cruising sppeed, usually of around 14 knots, and then work out the radius of action.
Parsifal, this statement is testimony of a poor understanding of range and endurance issues.
The best cruise speed depends on ship design and is also linked with a number of optimal wavelengths and the ready status of the boilers and not only with load, specific fuel consumption and buncerage as You suggest.
I pointed to grave, and I mean REALLY GRAVE differences in those definitions between navies and often even between classes of ships which are not reflected in Your source.
I see that you are beginning to include derogatory statements about knowledge and credibility. I am going to assume that I can do the same
It is obvious that you have an agenda here, which does not include finding the truth. I certainly agree that determining the "true endurance ratings is a complex issue, of which you are raising just one. Unless we are going to spend six months studying the individual characteristics of each ship, and the conditions under which their published endurances are arrived at, I suggest that we simply rely on the published figures. The boiler state certainly is an issue, but so too is the sea state, the salinity of the water, the numbers of speed changes made etc etc. The true endurance figures are NOT just limited by the selective grazing that you are wanting to engage in, and I am not that interested to go through a full six month detailed study to do the job properly. The result for me is to look at as many different sources, and make an educated judgement from there.
I would suggest that the sources (there are more than one, incidentally) are reasonably accurate, but that they are saying things that are not to your liking. Your reply has been therefore to engage in a selective grazing exercise, and not taking a holistic look at the whole issue. If you want to challenge the references like Conways, Janes, and the cruiser site (and soon the definitive work on cruisers by Whitney) then go ahead, produce the thesis standard rebuttal that you are going to need. Don't try to get me to do the work for you, because I don't have a problem with the internationally accepted figures, you do.
