I agree with consolidating definitions down to one unified "Responding Time" definition, as the true system quality attribute to measure and evaluate is the elapsed time between notification and arrival.

The terminology has not been completely updated to reflect this. Specifically, under 12VAC5-31-10 - definitions "Local EMS response plan" still refers to the old "interval" terminology. Also 12VAC5-31-610 Designated emergency response agency standards still refers to the old "interval" terminology.

Recommend ensuring that the updated rules and regulations accurately reflect the unified terminology of "responding time" to avoid any misunderstanding of the systemwide quality attribute that OEMS is promoting.
