My point is that they ALL will experience a change in ionic composition.

The question was: Which one will experience BIGGER difference!
You pretend you did not notice or you really did not notice?

I realize that one will have a faster rate than the other. My point is it
doesn't matter because they all are moving in the same direction, just with
different rates.

They also only say "limit". How much is it limited by? It could be only
2-5%.
