Right then. I have downloaded the entries and worked up a spreadsheet containing the guesses for Room A and Room B for each of our lovely contestants.

The formula for deciding the winner is -
Magic Number =ABS(384-R1)+ABS(628-R2) where R1 and R2 are the guesses for each room. The closest number to zero wins.

The winners are
1) Greg D with 84
2) Courage with 192
3) Ray with 202
4) Gazmick with 220

I’ll be contacting the winners in order so they can choose their prize.

Thanks to all for entering.
