A paper of mine did recently reach the final competition for the best paper award of a prestigious conference in my field. Although mine didn't end up with the best paper award, yet I'd like to note that in the "honors and awards'' section of my CV because the conference is arguably one of the bests in my field, and even getting through the roster of its finalists means a lot.
On the other hand, I was also the co-chair of one of the sessions of the conference. I had neither any impact on the selection of the finalist nominations nor any vote on the overall award process whatsoever. Since I'm a rookie Ph.D. student, I'd also like to quote this role in the "academic experiences'' section of my CV (next to my reviewing roles, TAships, etc).
Now I'm wondering if I take both ideas above into account, one may think that my co-chair responsibility would have influenced on my finalist achievement. How would academicians interpret this case? Do I have to pick one to avoid such a misinterpretation?
