Agreed. 771R 772M has been jumping around even on those days
when 971E 972C did not appear on sv925.
971E 972C occasionally goes to Sv975, and Sv925 gets random
DAF/OAC.
771R 772M should be KJDEP SP.
771R today on 190AM24, sub 1216X,
and 772M today on 975 (info by Benjamin Ong).
Ytd 971E was on 925 again and if i count the number of times
971E on 925, i think it appear on 925 for more than 10 times. 972C
also. Cant be a co-incidence that this 2 bus frequently cameo-ed on
1 service on a weekly basi when they are spares.
