I thought I had addressed this before previously..
Anyway, the issue is that 3354K apparently did Sv 17 for only
the first few days when it was newly-deployed onto the roads. After
that, it didn't do Sv 17 much at all, but instead went to other WAB
svcs in BNDEP as cameos to replace other svcs. I've personally
never seen that Wright on Sv 17 though, even during Peak, but i did
see it appear in other people's cameo lists on the first few
days..
And back then when we guessed 3354K was perm BN 17, the e-tt had
no change at all around that period. And given how BNDEP typically
don't run BSEP buses as outside-schedule buses (and hence means
e-timetables should have some changes if there was a BSEP add to
any svc), this means that 3354K was more likely a cameo on Sv 17
only for the first few days but we mistook it as perm Sv 17 because
of the assumption that BSEP buses will perm on the svc they appear
first on when they're newly-released onto the roads.
And I guess we should know by now that lately the depots have
been running around their extra BSEP buses like SP buses uh without
any perms.
I hope that clarifies your doubts. 
Bro, I don't go through every post, posted here. My point is it
took 3+ months for us to take it off sgwiki bcoz all this time it
showed BNDEP 17 PERM.
