What is the difference between the two lists?

What you can get to is a hard filter. Nothing you have not ticked is ever suggested. The list itself has two toggles, Hide what I cannot get to and Show everything, including what I cannot get to, so you can always look at the rest. What you already do only changes the order, so things you do come first and everything else is still there. Somebody who has never lifted a weight should still be able to find their way to it.
