Simon9x. In the across clues, the word “normal” indicates the grid entry length corresponds to the number in brackets. In the case of the down clues, because you have no visibility of their position in the grid, it is not immediately possible to discern what is or is not a “normal” clue. Suffice it to say that the preamble is consistent. So expect some down clues’ entry lengths to be entered exactly as shown in their respective brackets; others will be “compacted” so the entry is shorter. The wordplay still indicates the length of answer. Hope this is not teaching grandmother to suck eggs.
