One shared meter. Multiple users. Each person climbs their own slab ladder — paying the cheapest rate first, regardless of how much others consume.
Each master slab's units are divided by the number of users, giving everyone an equal "share" per rate tier.
Every user starts at the cheapest rate and progresses upward only based on their own consumption.
Meter rent, ED charges, and customer fees are shared equally — independent of how much each user consumed.
