I guess that interpretation is a bit harder than that - and I don't know how impenetrable the ATC operational logs are to decipher and match up with the NTK data.
There is also the strange category of " Number of aircraft arrivals operated outside the runway alternation pattern (excluding TEAM arrivals or emergencies)" which would be clearer if there was a bit of commentary explaining what was going on. I guess situations where they shift the whole landing runway from the designated one to the other becuase it is more suitable for cross-winds would be approriate to go in that box.
But there is still fog around.......
