Thats a feture not a bug, when you got all cards on high-end overclock you dont want them to stop or miner will crash
Sorry, but this have no sense.
Of course, i'm not excluding that you overclocking during mining in progress, but anyway no logics for me. Even from electronics engeneering view.
also you want max hash rate when it reconnects with isp.
Nice try

Mentioned hash rate is nothing - shares are important. Because it will be an average estimated hash rate of idling process which have not proven with real shares.
