The party chat is in fact for skillchain purposes (I wouldn't put it on a ward for example), and actually .5 does work and happens to be the lowest wait value acceptable. 1.5 does not work however, which is admittedly sad.

I posted the macro as sort of a template to demonstrate what is possible, as the spirit of the post was to provide a resource since I could find no current resources to begin with. Furthermore I wouldn't have posted it unless I had already thoroughly tested it.

If you want proof that .5 works try the following macro:
/jobemote RUN <wait .5>
/jobemote WAR <wait .5>
/jobemote MNK <wait .5>
/jobemote DRK <wait .5>
/jobemote PLD <wait .5>
/jobemote BLM

Or whatever 6 jobs you like. Have fun with it!
