Thanks everybody for the quick feedback, I'll proceed accordingly. For some reason, I get an error when I click through on the tool, so I never got as far as having the BA locator, which would save me having to run through each sector again on the phone. Other than not having QR on first flight and the lack of Australia/NZ flights showing up, are any of the segments below generally a problem with the online tool?
