I found this old article in Flying and found it quite helpful.

The Harvard has different Va for different controls/axes, if I recall correctly. From memory rudder/yaw has quite a low Va (95 knots?), pitch, which might be standard Va around 130 knots, and roll a higher figure 160 knots?
The article implies that Va is mainly related to vertical gust speed and pitch, although the other school of thought is that for modern certified aircraft Va is applicable to all controls individually, and you can exercise full rudder control, for example, at Va for your mass without worrying about bending your aircraft.
The old school seems to make sense and there are different Va for different axes/flying controls.
