Hello, Generally, you can tell when NuPIC is totally confused about input data when it simply repeats the last value it saw as the prediction. This is pretty easy to see in a graph, because (assuming you used the inference shifter) the prediction line is trailing the actual value line by one step.
I don't quite understand the rest of your question. When NuPIC just repeats the last line, it will not be correct as the input data changes. You can also look into using the MetricsManager (see the hot gym source code [1][2]) to get some error metrics out of the results.
