I was on the high end of a bracket as well but my order did not explicitely said I had 38% or 46%, ... just every other week-end plus this plus that plus this, ...

I did use the parenting time tracker here to show tha tit amounted to 46% of the time.

She tried to show that it amounted to only 43% of the time

The Magistrate sided on my side and did put me in the 45 to 50% bracket which is hudge if you think about it.

now all the future orders will reflect at least 45 to 50%, ....

the Magistrate only did cut my CS in 1/2 and used his discretion to limit the downward change but you know what? the new law also says that if there is 20% change and 75$ at least it's unfair well then I am filing every 6 month till they get it right :)

anyway, bottom line is that if this is not explicitely defined as numbers in your order, the bracket is argueable in court.
