Not sure how to 'balance drift', have never come across it, or maybe I am not familiar with the terminology. I will run through a quick scenario:

W/V 055/36 TAS120 TRACK085T VAR 7W

Firstly obviously, I have plotted the W/V onto the plate. It is absolutely BANG ON!!
Secondly, I spin round to a track of 085. This gives 11 deg of Stbd drift, and a G/S of 91kts.
This gives a True HDG of 074, so a Mag heading of 081.

So answer:
HDG(T) 074
HDG(M) 081
G/S 91KTS

Answer in book:
HDG(T) 077
HDG(M) 084
G/S 88KTS

So, I am 3 out on all calc's.
Do you guys get the same.......

Thanks a lot for your help.
