No problem.  Also, I go by Fredrik not Carl, a misconception that is
easy to make since I don't abbreviate it.  :-)

If you really think you can do it, then leave it as is.  If nothing
else your mentor will most likely let you scale down the list if you
later find out that you've bitten more than you can choose.

Oh, ok then.

It seems we are on the same page.  :-)

I only meant that you're on the right track.  So, yes, you're right!
