no, this doesn't make any sense. I'm sending well over 6 khs spread across 2 pools, neither pool is showing more than 1 khs for more than 12 hours now. I've been mining CN based coins for couple years now, and have never seen this.
It's very strange. I've used the official pool some time ago, and haven't seen any problems with the hashrate and income.
Now I use another pool (one from my list above) and everything is fine too.
