This is how I understand it as well and makes sense with what Reinheart posted above.
If you have 300 mil, it becomes 30 mil.
If you have 90 mil, it become 9 mil.
Person 1 still has the same % more then person b.
Everyone that thinks they just lop you off to 99 mil if your over 100 mil is dreaming. (think about it, how is that remotely fair lol)
