Should I put an explanation of an activity in the Additional Info?

<p>I have both 1) One activity that is hard to explain and a little obscure, that is really important to my life and 2) An internship in which I do some pretty important work and am valuable to the team.</p>

<p>I explained the first in my 150 word explanation. I want to explain what I do for the second as well, but I have nowhere to put it except in additional info (where I've also listed additional scores, clarifications of things, etc)</p>

<p>Is that just unnecessary/annoying, or should I do it?</p>
