7. The percentage established shall be the same for each rent in the building.
It shall not be less than 15% nor more than 25%.
However, where one or more assignments envisage the payment of both the electric service and the gas service, that percentage may be from 10 to 20% for each of the debts.
It shall be determined by taking into account the amount of the debt, electrical or gas consumption in the building and the costs contemplated in section 19.
If circumstances warrant, the judgment may provide a series of varying percentages and the dates on which they respectively become effective.
