2009-07-17 Couch Potato...
I have just worked out that at my latitude of 50 degrees, assuming my house includes its land area of about 30x40m, there is a 1 in 6.7 million chance of getting a couch potato award on a given day. Not good odds, though admittedly a little better than the Lotto jackpot :|

2009-07-29 More about Couch Potato
I think my previous estimate was pessimistic. Personally I would count anything within a 30m radius of the centre of my house, given that the grounds are fairly large. Actually they are rectangular, but likely to be equivalent to a 30m radius circle. I must measure this accurately at some point.

Anyway, this new criterion yields a 1 in 3 million chance on a given day (equating to a 1 in 8200 chance in a given year).

2009-07-30 How accurate are the co-ordinates?
I like to answer questions like this, so I had a go. By my reckoning, the geohash algorithm gives a maximum grid resolution of about 6 femtometres, which is about 6,000 times smaller than a hydrogen atom. Talk about a hammer to crack a nut!
