"Yet I think Tim’s single review was possibly as valuable as all the others combined".... and yet you don't even tell us anything about his review.... disappointing esp. considering the screenshots/level of details on other input.
On a different note, def. feel you pain regarding the copyeditor.
His review contains comments annotated on a book of 300+ pages. I don't think it would have made this section any better by deep diving into his review.
