Need some urgent help on this as I need to change plans overnight.

As the first part of my DONE4 I want to do: syd-lax-jfk-lax-lhr

The first LAX is connecting QF107 to QF3233, so not a stopover but a transit. After a couple of weeks in New York I want to rtn to LAX (as a milage run) and fly onto LHR.

When I enter into the trip checker I put syd-jfk omitting the transit. It works this way. Is this cheating?
