Human psychology is the problem

I'll use Battlehill as an example

GNE 41 and 41A

Since the last changes it has added 2 extra minutes to drive around Wiltshire Drive however physiological passengers think its longer and will opt against it if they can

Same as 309 is quicker vs 310 and 311 as they add an extra 3-4 minutes around Mullen Road and Station Road

Express numbers should be made more effective

Eg X39 is the 309 but as an Express to Cobalt

Same as X21 is an Express to the 21 service to an extent

I would say increasing stops would be beneficial
