I kinda like the stats doing this sometimes. It's kinda like Christmas morning, You not real sure what your gonna get when the stats update.
It could be a couple of 3 blocks or a crapload of sub 10 minute blocks

. Kinda ads some excitement to an otherwise boring mining career.
Dont think so, can you imagine how many people would expect certain results then get less and start moaning at btcguild ? It can be chaotic

Oh, of course if they get more than expected they will be quiet
