PUT api/CalculatedDevices/BackCalculate2/{id}?startDate={startDate}&endDate={endDate}&overwriteExisting={overwriteExisting}&includeDeviceProperties={includeDeviceProperties}&evaluateReliantDevices={evaluateReliantDevices}

Handles back-calculating readings for a specified Calculated Device (covering a date range specified by the inputs) and returns the number of new readings made.Note: It is recommended to use this if back-calculating a large quantity of data. This does not return the new readings in the response, only the number of new readings made. If back-calculating data over a small span of time or the results are desired, consider using BackCalculate.
