Surreysinger, two thoughts:
1) It was on a national programme, so (though I do take your point) I think it's fair game for someone not in that area to be heard from (especially to point out -- as you do -- the "should" vs "can" aspect of the remit, as well as a number of other basic flaws in Mr Thomas's comments).

2) I respect and admire your thorough approach, but I also think what you have already written is quite good; it would be better to send it in with a few tweaks than to not send anything because of the additional time involved.

Cheers,

YY
