Depends on the length of the outbound/inbound legs. As you can't correct for tracking errors in the turns, you must allow for the drift during these turns on the outbound leg. You don't need to correct for the inbound leg as you'll be tracking the beacon. Now for the maffs, bear with me.....
Both turns are Rate 1, hence you'll spend a total of 2 minutes in them. The aeroplane I usually fly flies around the hold at 180 knots TAS; a 3nm outbound leg therefore takes 1 minute, and I must therefore apply 3 times the drift, as I must do 3 minutes worth of correction in 1 minute. The basic drift is calculated from consideration of max drift (wind speed/groundspeed in nm/min) and the clock rule described above.
Similarly, a 4nm outbound leg at 120 knots TAS would take 2 minutes, and you'd therfore apply double the normal heading correction. Hope that all makes sense; feel free to point out if I've missed something or am at all unclear anywhere.
