I assume that this is sarcasm. But seriously, if knowing the true wind direction is a waste of time, how do you know when to tack and lay a mark or channel without having a general sense of the true wind direction.

The ambient wind vs gust discussion derived from a discussion of NOAA weather station wind readings on a particular day. Understanding predictions and recorded wind conditions in standard terminology allows you to better understand how to set up your boat based on the predicted or experienced conditions.
