Powershell Try Catch in nested code and how to

I was writing some powershell (quite a lot of powershell actually) today and had to go through the code of someone else.  It's always nice to see how other people are doing stuff.

So I saw this piece of code with try catch.  Although the piece of code worked, I didn't agree with the approach.

Let's see what the approaches are and what's the best way. Comments are highly appreciated.

WFA Volume AFF efficiency command
