I don't understand what you meant by
leaving it at last value read?
System doesn't use those "values" as depicted here, this is only a recorded sample of several sources used. Sensors are always sensing something, at any time, when they are not physically failed. Their own output rate is many times higher than that.
If, at one point, an output needs to be considered invalid below a certain level, there is obviously a potential logic about not using it. Now, there is certainly also some room to improve this logic as far as SW is concerned.
