Maharera: Rera Payment Schedule on Pre-Rera Registration

Whether RERA payment structure should be followed or not in case of pre-rera registration and post-rera demand.
old(pre-rera) buyers suffer loss due to loss of interest on early payments(99.5% on last slab)

Builder took around 95% of agreement value on 28th slab and around 99.5% on Last slab(30th Slab)
Agreement was pre-rera dated 08-March-2016,
28th Slab onwards demand was post-rera.
As per my understanding of maharera payment structure only 70% payment should be done till last slab.
75% demand should come on completion of of the walls, internal plaster, floorings doors and windows
75% demand requirement is still incomplete in RERA website for this project.

Builder disagrees mentioning that agreement was done pre-rera so they follow agreement payment structure.
Please provide clarification on the same, whether RERA payment structure should be followed or not in case of pre-rera registration and post-rera demand.
