I'm between appointments on a very busy day of hard work, so best not to suggest wording now ... we could put it in quotes if necessary?  Also, if we are to use this source, can we work in the strongest conclusion, which is really that a closer look is needed ... lest we leave the impression this conclusion is "a done deal"?    It doesn't seem that firm ... will leave it in your capable hands because I'm so swamped today.  Best,  (Talk)
