Most likely result for Chile IMO: 1 medal: Men's Artistic Gymnastics - Floor (T. González)
If being optimistic: Men's Floor (T. González), Women's Triathlon (B. Riveros)
If being very, very, VERY optimistic: Men's Floor (T. González), Men's Vault* (T. González), Women's Triathlon (B. Riveros), Women's Shot Put (N. Ducó), Women's Skeet (F. Crovetto).
* Not sure if González will do Vault in the end tho, but if he does he might have a chance for medal.
