In the Rule 2.9, ‘The Continuum’, change the line:

A Traveler may, no more than once every seventy-two hours, edit one Formula in the GNDT, as long as the resulting Formula is legal.

to

A Traveler may, no more than once every ninety-six hours, edit one Formula in the GNDT, as long as the resulting Formula is legal.

A slight change to make the Formulas a little more valuable. I propose that we change the waiting period from three days to four (and possibly longer after we see how this may work) to encourage Travellers to make use of all the Formulas for travel.
