The live update is available through the LiveUpdate system.The mode of mathematical calculations assumes a blank run of the tester, with call of functions OnInit, OnTester, OnDeinit. With an empty run, an agent does not synchronize the historical data. The mode of mathematical calculations implies an automatic use of a custom optimization criterion (Custom max, result of the OnTester function) to determine the best possible results. Previously, for such a mode, it was necessary to specify the testing start date larger or equal to the testing end date, and to manually select Custom max for the optimization criterion.
