I hope he doesn't mind
Not at all - it is interesting to compare the results of different approaches by different people both of whom were "trying" to be "objective"! I think it is worth our while seeing these different approaches and results before confirming all our own assignments - we may well decide to stick with our own assessments (and have the right to) but at least we will have had the chance to "calibrate"!
As you say - there may be reasons for different extreme numbers which are related to number/continent of WHS seen by each of us. Regarding my very high median figure - that is likely, at least in part, to be because my assignments are still "Work In progress" - I set up the M.O yesterday and and have done a single trawl through together with a few targeted comparisons. I would expect a number of the 2.5 ratings to "migrate" before they are finalised (both up and down). I am hoping to go through "subjects" like e.g Wooden Churches, Castles, Cathedrals, Colonial Towns, European Cities, Palaces, Gardens, African Cultural Landscapes etc in order to see if a bit more differentiation is justified. But I suspect that I will never totally escape the result of deciding that an "average" WHS deserves an "average" rating.,
have kept my own rating (1-10) since 2011, so am comfortable on those.
And you don't feel the need to change those "initial assessments" from a relatively long time ago in the light of your subsequent travels and "learning"??
