It is not constant, but I too have noted your observation.
On the pontoon at waterford we were travelling at 2kts, at anchor after going wide and hitting the sandbank at Shell Island in North Wales I had 3kts speed as the tide flooded and we waited to get off and follow the correct route into the harbour.
Yet on my mooring, we have enough current that needs often full throttle on the dinghy to get alongside, nothing, nada, the log does not read at all.
Even if I clean and spray ptfe, so it is not down to clogging.
My thoughts are the log must need to be exact with the current, at anchor we swung dead on, but my mooring is a trot, so might be just off. Though, we always seem to get all or nothing, I would have thought, just off current we would have a low reading.. also, the boat swings back on forth on the trot and the log never (so as I have seen) springs to life, I can't believe we are never in-line with the flow.
