You do know we have been trying to keep the LOD hack runs out of the mobile benchmarks right?

No I don't honestly. NVI was used for OC as an substitude for AB. Can you link me to thread where it was discussed? According to HWBOT rules LOD is in allowed optimisation for Firestrike anyway. 

It's considered common courtesy to keep mobile system runs valid. Till today everyone has kept it that way across all hardware generations.

Mobile world is not as cutthroat as the desktop world is. So we try to keep as close to legit as possible. One would not game running LOD where you can't see anything, so we do not bench that way either. Again, it's a common courtesy situation only for mobile benching.
