Ah, and yesterday was under 20 too. That's good to know. I hadn't realised there was a firm link to 20 and just assumed it was the closest 'warm' guesses each day. Both days were hideous slogs of the type that make me wonder why on earth I play this game, and DH went over 500 yesterday without getting the word!
Junior yesterday must also have started under 20 as no tepids there, and a stupid number of guesses with awful greens. Today I got it in 6 so no tepids to be seen either!
