Еще вопрос: а почему команда list explainmagnitude дает значение 148, а внизу кошелька при майнинге только 124?

#1: Explain calculates it manually at that exact time and breaks it out to let you try to diagnose problems with each project mag.
#2: Main window calls for your current mag from the consensus each time your node switches (mining) boinc projects; so it reflects the consensus mag (IE what 3rd party nodes think your mag is) at the time of the GetNextProject().
