pool is back up, and the miner is not measured in hpm it is measured in collisions per min. As explained by freetrade "I've made some updates to code to count collisions per minute rather than hashes per minute.
Some hashes generate 0 collisions, I've seen others generate up to 8.
Hashes per minute is a good metric to use if you're tweaking the speed of an algorithm.
Collisions per minute is a much better metric to judge your chances of finding a block. It is also much better to use when comparing algorithms which is what most end users of solo and pool miners will want to do."
