a. Procedure Turn (45°/180°) Consisting of a specified track & timing from the facility or fix, a 45° turn away from the outbound track for 1 minute from the start of the turn for categories A and B aircraft (1 minute 15 seconds for categories C, D and E aircraft), ....
As for drift in a holding pattern, I can count on the fingers of one hand the number of times I've had to hold for real. Finding that I rarely knew the actual wind to apply a

Whilst inbound, given one is tracking a bearing or preferably a radial, the drift is easy to determine, and then apply on subsequent patterns.
I found that this frees brain space for other considerations.
