i dont think just holding the outbound track will help. on the inbound its fine as your using single drift inorder to maintain a track.
for the outbound leg of the hold, use the wind arrow to work out your drift angle and time outbound so by the time your over the beacon again its 3 minutes.
its very hard to say just hold the track as the wind you used on the ground may be different so you need to work it out in the air. your flying the heading you worked out as you have taken into consideration the wind in the turns of the hold as well.
not typed out very well but its 6am and im going to bed..night!
