Each time I reopen analysis and setup the same fitting procedure for the same data I get the same fitting parameters (as one would expect) but with different fit errors. Given that the regression parameter estimates don't change each time I do this then I wouldn't expect the fitting error to change either. I have deliberately omitted the use of any error values in the 'series condition points' (Data analysis -> Rate analysis -> Edit Exp. Series) as I gather these have no impact on the fitting procedure or the fitting error at this stage.
