You need to consider your requirements.
If it is important to get a value returned at 10:30 when you only put
in the one value, then yes, you will have to use a large xff value
(at least 0.97).
However, that means you will still get a value returned at other
times when 29 of the 30 samples are missing - or 25 are missing, or
10, or ...
So you need to consider whether it's more important to have the value
- or to show that input data was missing.
