That is a great result. Might be a bit of luck involved, but hey, if it works out for you and you're spreading out the hash power between pools, then perfect!
I'm guessing the pool has not had issues with stability? There were a couple of pools with stability issues at the beginning for a while but seems to be getting better now that the pools are a bit more established. Asking because I'm looking for a reliable 'set and forget' type of pool.
