This report has been prepared in response to a request from Panagiotis Spentzouris, head of SCD, to review the physics performance of the native Kalman Filter in LArSoft. In response the author conducted a preliminary investigation that resulted in some specific recommendations, detailed in this report. The report also recommends that that no additional review is necessary until the recommendations made in this report are met. The most important recommendation is that the appropriate stakeholders develop a Kalman filter that can be used as a final fitter; the existing code redoes the pattern recognition and cannot be used as a final fitter.
