Hello all.
The preamble:
Twelve of the clues are missing a letter that solvers must restore before solving, always making a real word; wordplay in twelve further clues gives the defined entry less one letter. These letters, taken in clue order, COULD BE helpful for the remaining entries, whose clues are otherwise normal. Numbers in brackets indicate the length of entries. Chambers Dictionary (2016) is recommended.
Three types of clues then, and some answers will be modified. This COULD BE fun!
REAL and REPLY came early, and I noted that these were both two letters too short for the space available. Once I had solved IDENT I saw that I could add EVs to give REVEAL, EVIDENT and (with the help of Chambers!) REPLEVY. That also shed light on an entry I had been struggling to make sense of: PRIMEVALLY. It was all much easier from here, although I did make good use of the emerging message to help me in the NE corner. This message revealed itself to be:
WHAT COULD BE WORTH ENTERING?
Well, by this point I knew the answer as I had been merrily entering it into the grid where it fit: EV!
And of course it could be worth entering* your completed EV into the competition. Nicely done.
Certainly I found it worth spending the time entering the letters into the grid. Thanks Jaques!

*I might enter if I could actually source the puzzle from the puzzles site rather than having to resort to a screengrab from PressReader. But that’s just how things are, no use grumbling. Grumble grumble …
thanks for puzzle and blog! I decided that EV=Expected Value and only then did the engimatic variations penny drop
If we are in confessional mode, then I will admit I spent ages trying to work out why I had to insert ‘electron-volt’ or ‘English Version’ into all those answers!
If we’re in confessional mode, I once … on second thoughts, maybe not!
