I think I'm going to try 1.75 today because Salem's pre-shot an hour ago was 160 on ReliOn and 250 on AlphaTrak. Now it's 155/225?? Is it normal for it to just go down like that? I mean I know it's not by much but still. I don't want to not give him anything but it's staying pretty low. Also do the two meters normally have that big of a discrepancy? I'm mostly using the ReliON for everyday stuff but I need to use the AlphaTrak to give the vet some numbers since it's what they use up there.
