We've been over this quite a few time now. You don't seem to have yet grasped the difference between time dependent deterioration of a hole and differential sticking.

Differential sticking isn't time dependent like some mechanical hole deterioration is. On the main bore, mechanical deterioration prevented the RCX getting down.....delays due to BH a factor. BUT...bearing in mind they were running a higher mud weight than in the side track there's a very high chance if they had got the RCX in the hole they would have faced exactly the same scenario they faced in the sidetrack...differential sticking of cable and/or tool (in no way attributable to BH).
