0001 The invention is concerned with a reliable manner of monitoring an injection process executed by means of a variable dose injection device with feedback means for generating a number of feedback events proportionate to the dose to be determined. A dialed or injected dose is determined by measuring a first signal of the process comprising a first signal peak related to a feedback event; detecting the first signal peak in the first signal; selecting an evaluation interval comprising the detected peak and adapted to an expected peak duration; deriving, from the first signal limited to the evaluation interval, a feature or characterizing parameter of the feedback event; identifying, from the derived feature, the feedback event as one of a dial up, dial down, or expel feedback event, and counting the number of identified feedback events to determine the dialed or the ejected dose. The two-stage approach with serially executed peak detection and peak identification separates an initial localization of a signal peak possibly related to a feedback event from a subsequent analysis of the detected signal peak in view of a possible source or origin feedback event, and allows to optimize data storage and processing power requirements.
