Another point to add on is that, I observed too that on average
the Wright indeed spends less time at each stop compared to the
KUBs/Citaros to load the same amount of pax. Abit like "duh~" I
know. But it does help the Sv 39 BCs to keep to their frequency
better.
I've not seen any bunching during
AM Peak yet so far, which is a good sign, especially when it's
kinda common to see 2x KUBs bunching tgt last
time. 
I do wish they do
something to their Off-Peak frequency though. Not sure if it's
related to the H1 schedule, but during Off Peak (especially mid-day
& early afternoon), it's kinda normal to wait for 20-25mins
nowadays for a Sv 39, even though the E-timetable says
otherwise..
I have ever been saying this.
During peak hours DD is faster than SD on crowded services. I
noticed this so many times that SD crawls at each bus stop once it
reaches 65 pax. People have to alight, then those near front door
have to move back for new people to board. Hence, most SD services
are highly notorious for bunching.
