What is your understanding of light gathering?

I’m surprised how much Wikipedia contributes to the forum.

Not sure how to put it, I guess luminosity? Basically, with the two setups, assume one is exposed correctly to get a nicely lit image, the other will have the same.

Promit wrote:

The amount of light gathered is 4X on the FF sensor in this case, which will lead to a two stop idealized improvement (the ISO 200 on FF will look like an ISO 50 m4/3 shot, all else equal). The exposure will be the same for both cameras.

This is exactly what I wanted to get clarity on, but I think if you mean light gathered is 4X, then you should mean ISO 50 on FF and ISO 200 on M43?
