Yo do not seem to be worried at all about the bits than are higher that your advertised hashrate.
It's just the way pool calculates your hashrate based on submitted valid shares. Pool does not know what hashrate is your miner doing and it cannot ask the miner as that could be open to abuse with somebody modifying miner to report higher than actual hasrate so instead pool calculates it based on submitted valid shares. Sometimes it will be bad luck and you will not get share for a while or error in calculation or outdated share. Or the pool might be busy and not calculate hashrate and than include your valid shares in next calculation block and show higher hashrate. Sometimes you will see smooth hasrate, sometimes you will see couple of dips, other times it will all be spikes and dips, it depends on pool the renter is mining. Also if you are mining with GPU's you will see dips when it's mining dev fee. As long as the average hasrate is were you expect it to be it's all fine.
Here is a picture with 3 examples.
