How to determine Chithasikas in Naama?

We know that there are combinations of Cetasikas that are used to identify different Cittas. I want to know how to determine Cetasikas in a naama who is having the udaya waya gana (or steps ahead like bhanga khana ). If we consider one naama, there are multiple cetasikas in different amounts.If a person can see naama with their meditation power, how they ditermine what are the Cetasikas in one naama and what are the amounts were there. As a example, lets suppose that the meditator had a "somanassa sahagatha Khana(Gana) sampayuthha asankarika" citta (This is having 17 naama). How to determine what are the cetasikas were at each of 17 naama, out of 52 cetasikas? We know there must be Aloba, Adosa and Amoha cetasikas in naamas at previously mentioned citta, but how to determine the amount or the power of these cetasikas? I think it must be a really tough exercise and very tricky one to the meditator. I would like to know the strategy in step by step. I need abidhamma expert's answer.
