Correct use of GMT Master

[SaddleSC]

I was perusing the Rolex web site last week and downloaded an application that teaches you how to use your GMT. I was always under the impression that the best way to use the GMT Master would be to:

1) Sync the GMT hand to your local time zone.
2) When traveling set the Quick Set hour hand to the new time zone and then continue to read your home time zone using the GMT hand on the 24 hour bezel.

The Rolex instructions suggest the following use, which actually tracks 3 time zones:

1) Set both the hour hand and the GMT hand to GMT time.
2) Then use the Quick Set hour hand to step back (or forward) to your local time zone.
3) When traveling, rotate the bezel to track the home time zone using the GMT hand and set to local time using the Quick Set hour hand.

Just curious how do most of you guys use your GMT Master? What is considered the correct way?
