Making sense all the instructions is proving a nightmare since they are so open to various interpretations. The only one that's clear is the first one. However I interpret the phrase from the six extra words (including the method advised earlier in this forum) I end up with a sequence that has nothing to help form a new 1across, for example (and I think there are only 7 new possibilities for that). I assumed from the preamble's 'right order' that the first two letters acquired from original paired clues would start 1ac, but that doesn't seem to be the case. Am I completely on the wrong track?
So far the only feel-good moment was the application of the first instruction, which proved neat. There was no pleasure to be got from the clues, which have some of the worst surfaces I've seen in along time.
