I'm not really scoring very highly in national terms - my highest total score is the 1991 non-clearance which prompted me to start this thread. I'm not sure about highest individual sum but only around the 300 mark I'd say. Out of interest, how much does that 9*9*9/8/7 combination score?What is your record score? (Overall, and also individual sum?)
I got the closest yet to a clearance at the weekend - four numbers left, with no operators, that added up to 12... But as you say, close is nowhere really. I'm not going to give up trying however!
