Hello, On Mon, Nov 14, 2016 at 02:22:16PM -0800, Shaohua Li wrote: > cg1/cg2 bps: 10/80 -> 15/105 -> 20/100 -> 25/95 -> 30/90 -> 35/85 -> 40/80 > -> 45/75 -> 10/80 I wonder whether it'd make sense to make the clamping down gradual too (way faster than the ramping up but still gradual). The control model isn't immediate anyway and doing the other direction gradually too might not hurt the overall control accuracy all that much. Thanks. -- tejun
