People have different ways. Here's my process...
1. Reference your holding fix, calculate your present QDR and range.
1a. Reference groundspeed in nm/min and calculate time to fix.
2. Place grubby fat fingertip on chart at approx your position.
3. Say to self, "Coming from here!"
4. In mind's eye, superimpose the 70deg dividing line which Jepp leave out, and Aerad include.
5. Is it L or R? This should make your type of join clear.
6. Reference again your time to fix, think about your actions after overflying the hold. Downwind 'hack/abeam' QDR? Wind Correctives? Gate position? Radio calls?
7. Bear in mind the wind if its just between one or other sectors. Join is determined by HDG. Within 5deg.
Hope this helps,
