Can someone enlighten me about my problem with this timetravel&coin regarding mining?
Stopped mining it some time ago and now I have the same behavior again.

My fairly straight constant shown hash-rate from ccminer, with 130-150Mhs, ends up as  an endless loop of 30Mhs - 110Mhs on pool side. I mean even then when the rest of the pool is at an constant rate.

Can't say that it has any rational relation with current coin difficulty.
It looks like supernova pool + ccminer are not optimized and wasting a lot by irrational difficulty jumps
Sometimes every minute I get a new difficulty by stratum.
My fun 2 card rigs are shown, on pool, at the same time with way higher hashrate than my x4 or x6 rigs. All with 1050Ti(4GB).
When I test a new version of the miner everything starts out with expected hash rates and then after >10 minutes it starts to fluctuate.

The only thing I can think of is lowering i way below 20 but that did not change anything at my first trial with this coin.
I also tested some GTX 960(2GB) and 750TI(2GB) and also single cards which have the same behavior.
Its a little bit strange when a single GTX960(2GB) has an higher hash rate than an x6 rig with GTX1050Ti

Tested it with own builds and also official releases based on tpruvot/ccminer from beta 2.0 upwards (windows and Linux, different drivers,OS, different internet connections etc.)
