Whatever the issue is I havent had it with other leased LRP rigs and I never got a message or email about the issue until I checked this thread. Other rig owners have been amazing with communication and understanding, unfortunately for this reason and the above reasons I will not lease this rig again.
If provider is using LRP with share calculated speed (default), then speed will fluctuate.
Djezo already highlighted this in his thread that the speed is base on accepted share which will fluctuate due to rejects. That's why i provided you my live screenshot for you to check if there is an issue with my rigs. The last time i check, it was hashing perfectly.
