The term Egoic Separation refers to the subjective sense of identity that comes when a monad within the Fabric of Consciousness intensifies to the point of self awareness, and then differentiates as a result of experience. The more individuated a monad feels, the less a subjective "identity of oneness" is experienced, and the more separated and individuated that monad is.
It is possible to operationalize this sense of separation. If you think of a scale between one and ten where one equals total identification with god (e.g. I am God) and ten equals total egoic independence (e.g. I am Michael Sharp) then you have a construct that can measure this important psychological variable.
