I wonder how random the "atmospheric noise" generating the numbers actually is. I've had five rolls so far - 4 w/two dice, 1 w/single die - and I've gotten doubles three out of four times with two dice. It's been 35 years since I took statistics, but I'm thinking the probability of that happening should be lower. Luckily I'm making steady, if slow, progress. :) Hope your luck improves soon!

But now that you mention it, that does seem a bit off.
