I was really excited last month when my M-spike suddenly dropped down to 1.1, but I kept saying to myself that it just didn't seem right. It had to be a fluke or some kind of a lab error. Looks like I was right; this month it is 1.5 again. Sure, I'm disappointed that it didn't keep going down, but I know that 1.5 is still totally OK.
Stable, stable, stable.
