Is there any way that one could set up how often does the miner do the switching - for example only 1 per hour? Or is this decided by the pool itself?

Namely, I've notice that some times it switches ever 5-10min (I've mining only 2 different algos) and given the fact that not all cards rump up immediately the rig is working let say with only half of hashing power. And after several minutes when all cards are up to speed the miners already switches to new algo... effectively this means that rig is hashing not with full but lets say half or 2/3 of power. Wondering if this is still more profitable vs possibility to set up switch to happen let's say max 1 per hour?

thx
