Uh. I think you did miss out a few weeks in beween your
observations. There was a period of at least 2 weeks in which 9462S
disappeared totally from 225G, and 8642X took its slot on 225G. You
can check other people's cameo lists to double-check
this.
What happened after that to 8642X I'm not sure. In fact, have you
seen 8642X running anywhere recently?
there's definitely changes to 225's fleet last week no time to
go down Bedok. But this week will go and see and will updated
changes most likely affected are 9462S 8642X and 8568C
