SMU13 reports SocketPowerLimitAc/Dc as the default power limit, but MsgLimits.Power may carry a different firmware bound for the same PPT throttler. Using only the socket limit for both min and max can therefore expose an incorrect power range. Keep the socket limit as the default, but derive the range from both values: use the lower value for the min base and the higher value for the max base before applying OD percentages. Keep the current limit query independent from the cap calculation.
