Given that there is no way to create an accurate list, I usually advise clients not to show such a list.

How accurate is the block in core? Doesn't it still show users a few minutes after they logged out. It's not a problem to create a view with the same functionality.

You could also add more filters, like one to hide users who have chosen so in their profile settings. Without that I'd also not recomend using that block.
