drift Alignment and CG-5

Since the original drift alignmeny post is getting far in the field here, I
am wondering if
a drift aligned 144 tooth CG-5 cheapo mount will hold a DSO for good picture
taking for say
5-10 minutes? I never see any exact reports about this. And the ones I
have seen are poorly
written and don't even mention drift alignment. The state of reporting on
this for the CG-5
leads me to believe that they are only good for 3-5 minutes of exposure
time.
