Does Tibs change buses very week?

I noticed that in the case of service 188, it seems to change buses once a week.

Every weekday at around 7.40am along AYE (opposite block 426, towards CCK), first week of December came TIB 1202K, second week come TIB 891C, and third week (last week) come TIB 1087B.

In this case the buses you saw could be the peak hour buses that would probably end their trip after reaching CCK. I do not think any of these buses are regulars of service 188.

Some services like 969 gets bendy buses from other services which operates them during the weekdays.
