Idk what you meant exactly by your first sentence. I mean, you
do know that those Sv 10e buses like to inter-change their x-over
svcs between Sv 10 & Sv 23 right? 
And the second part, I can only say that CGBP is quite a mess
lately in their new Wrights' deployments. Sv 8, 10, 23, 65, 81,
291, 293..those Wrights perm on these svcs like to inter-change
among themselves week after week in the past few months. It's not
the usual cameoing of a few days, but those buses can do weeks-on
on a certain CGBP-based svc and not be perm on that svc.
Yup I do know that. :) But I meant was that I noticed that sv23
likes to take sv10 perms like 9481L, 9578S..9636H..to cover the
missing fleet in 23. Sort of not wanting sv23 to take in the newer
buses from spares.
Guess Bndep has a bit of a problem with the missing DDs and the
spare DD buses that they have are not able to cover. I can see a b1
euro V kub on 12 in the afternoons, sometimes spare and mostly from
358,359..and also 904T has been on 9350G slots these days..not sure
are they cutting down the DDs used because on these 2 services as
there are a couple of bsep DDs on them. Hmm..
