If it is in there, I have not found it yet, but I would like to see some place to track observed wave height. It would help train everyone to correctly estimate what heights they are actually seeing instead of all the wild guesses we all have. Of course this info is unlikely to change our routing, just good-to-know info. My B&G P9 compass or other fancy multi-axis compasses ought to be able to provide enough information for this to be computed.
