Thanks for your reply, Ionacarr. I don’t think I am likely to be the next jumper-for-joy, but you never know. I agree that some of the members of this forum are not being as helpful as I think they would like to be.
Your suggestion for entering 8 is interesting. I thought of putting three letters in one cell but can’t see any justification for thus going against the normal conventions. It would open the door for doing the same all over the grid and causing even more uncertainty than we already have.
If we do allow 3 in 1 I would be inclined to use the third cell rather than the fifth. That would avoid clashes in the fourth and fifth cell as well as the ninth and tenth. But I’m hesitant about suggesting this as I have so many other grounds for uncertainty. I still think it better to give up and do something else!
