when mining in a pool why does the percentage go over 100%? is this because the pool workers are looking for a new block or still solving the current one? Forgive me if it seems like a stupid question..just trying to learn the ropes here.
Since you're rather unclear with what you mean with "the percentage", I will assume that this means some form of measure of the elapsed time since the previous block found by the pool relative to the estimated time to find a block with the pools current hashrate. In that case, the answer is simple: Bad luck. Mining is a lottery, sometimes you get lucky, sometimes you don't.
