I've made a slow start on this one, largely because I was heading back from holibobs so have only given it quick glances on ferries and the like and haven't really had a chance to concentrate properly yet. I can see it's superbly constructed though, if only from the fact that there are quite a number of clues where it's quite hard to see how a letter could be added at all! Looking forward to getting properly into it now.
One quick query. I see the rubric adds that "Numbers in brackets are the lengths of grid entries". This confirmation is usually included when there are clues that need something doing to the answer before it's added to the grid -- something removed, added, or reordered. However, as far as I can see, once the missing letter is restored to each clue it is simply solved and the answer put straight into the grid without change. That's certainly been the case with the ten or so I've done so far. I'd be grateful for either a reassurance that the remaining clues are indeed just solved and entered, or for a hint/pointer to a bit of the rubric I may not have read carefully enough...!
