Narrative:
The lca captain and I (first leg of my IOE) had just returned from break and were briefed by the relief pilots that the turbulence we were in was being caused by the wake of a super 380 in front of us which was further right of course than us with a right to left wind. The thought was to go further right to get behind him so we would be out of the wake; so we went R3 on the slop and did get out of the wake. We then received a message from ATC asking how far right we were and replied R3 and next message from ATC said R2 was max slop so we returned to R2 and sent a reply stating we were returning on course. By this time the super in front of us was now left of track so we [were] out of his wake turbulence.
