The problem with the number of briefcases to be opened in the UK could be that we find less narrow bounds for the contestants risk attitude due to the "big steps" in the game that are taken with each round. However, this range not only depends on the number of briefcases, but also on the pattern in the bank offers, so I'm not sure about the exact consequence.
MisterAl, I'd like to receive your Excel file, that would be great. Of course we will watch all shows ourselves, but your information can serve as a preview and as a check. My e-mail adres is

It will take some time before I can post some outcomes, but I will leave a notification here.
