When I've changed the basals on Ian's pump the total on care link does not match the total displayed on the pump. they're off by .025 which isnt' much but it's annoying me to all get out why this is. When I do the math myself I come up with what carelink shows: 12.750 The pump itself shows : 12.725 Anyone know why this is? I have 30 min periods so I wonder if carelink (and I) just can't handle that math? or if the pump is rounding things off in a way which I don't understand. I mean, the pump should be right - it is the one delivering the basals. But why the mismatch and why can't I make the numbers work - why do I get exactly what carelink gets?
