Using a 60 minute average of profitability would be better than relying on either the instantaneous value when polled or the strange attempt to average the 24 hour and instantaneous data that NemosMiner and others are pursuing. However, MinerControl appears to have been abandoned several years ago while MrPlus has been working on a fork of NemosMiner* right now and so seems to be receptive to implementing good ideas provided by the community so I am giving it a shot now.
