squawk, you don't use YMMB much do you? the end of 35L extends past the taxi way (before the taxiway was modified) and that intersection is the classic place for runway infringements which are a perennial problem for newbies at YMMB with its Five runways and multiple methods of getting just about anywhere. If 31 is in use then you will be crossing 35 L&R & 22 somewhere.
the startup request was brought in because the circuit limit is about eight and things can get quite busy some days.
