      There are a couple of "strange" strings that are actually pretty common: #INF, #NAN. I know what they are (calculations that result in infinity or undefined values--'not a number'--respectively). #IND was new to me, but Googling indicates that the C libraries used on Windows report #IND for not-a-number im certain circumstances.
      There a variety of explanations for this, all depending on the input data, and they are not necessarily bugs.
      When using lp.stacey in window mode, it is quite possible for floating-point precision errors to accumulate. This is also an issue with other objects that maintain running averages and the like. I seem to recall average~ having a similar issue that was discussed a few months back.
      I will take a closer look at stacey's code to see if I can handle these problems in a way that is less surprising to the user. It would be extremely helpful to have a data set that produces the error.
