did you realise how difficult it is for buses w/ better frequency and having to pass through difficult roads like Tampines Ave 4/ Tampines Ave 5 to maintain the headways properly? Even 179 can have 3 - 4 buses brunching during acad sem time during the AM peak by the time bus leaves NTU campus... Till to this day, you still can't explain 911's erratic freq... 3 - 5 mins but in reality it can be 10 mins per bus...
3-5mins after observations ONLY occurs from 5-6pm. Likewise for 6-6:30pm, it's more of 5-20mins, thereafter 6:30pm to 7:15pm, 3-15mins.
There's obviously lack of buses running AND poor allocation. There's only 6 buses running, 1 on rest. Out of the 6 buses, 2 are SDs. And incase you're unaware, CIQ area cock up a little can delay the arrival badly. You throw DDs on the svc, lagi worst. And the delay from 6-6:30pm are normally caused by the gap after the last SD n first Bendy.
