But if the AI/AH is working, chances are the DG will be, so the timed turn won't be necessary!
I guess that if you do as your instructor taught you and keep all turns gentle, you won't exceed 1g by enough to make any difference - how accurately can you hold that rate 1 turn on the TC anyway? It's a bit like flying a PAR, when the talkdown controller (bless her cotton socks) says things like 'turn right one degree, heading 003'...
