Hi @Yuval, welcome to the forum 
Indeed, as per the testing notes in the data file,
What’s the intended use-case/end result here?
Performance while moving is a full “space” rather than a simple relation (input → output) of values, so is difficult to measure and quantify in a meaningful way. The water can be moving at different speeds, in different directions, and with varying levels of turbidity, and can also include particulate matter, which may all have differing effects individually and together. While it would be possible to measure performance in a particular set of conditions, even measuring the conditions themselves accurately is challenging (speed isn’t too bad, water direction and turbidity are difficult, particulate matter is an additional issue). Covering the full space of conditions that people are likely to come across includes many combinations with complicated setup and measurements, so isn’t something we’ve done at this point in time.
If you’re after a transient response or similar, these are the best resources I’ve come across previously:
