It takes just under 4 minutes at a medium pace to get from Gate 41 to the entrance of the Oneworld/QF F lounge, which is right at the TBIT end of the connector.

IMO there's no need for the shuttle bus anymore. Escalators + elevators at both ends, + 2 short moving walkways at the inclined areas. Also, G2 staff (the wheelchair people) were walking back and forth to familiarize themselves with it.
