I think what atropos may have been trying to say is that significance is not really the deciding factor in what items go on and what don t It s true that items should generally be of moderate to great significance to go on OTD And generally speaking if there is a very clear difference between significance and both are well written we would choose the one of far greater significance On the other hand there is a very large grey area of relative significance where we avoid treading and if an item is of sufficient signifance for OTD relative significance is probably the last area we will tread anyway We will usual look at things like balance etc first If there are two or 3 items from the UK or US or China for example we will probably only choose one if there are lots of other stuff from other countries even if the UK or US items are arguably of more significance then the other items
