So the debate on bigblocks dual core r15 using benchmate being legit or not and where to put it I played with it myself.
12 runs for each scenario. As you can see benchmate makes a better average while maintaining the same max! Slot machine time maybe coming to an end!
The realtime issue occured for me as well. It scored very high using it 1132-1133 but was marked invalid when I saved. Depending on what is done for realtime or if it's able to be solved we shall see but this certainly is more consistent without exceeding the previous max without benchmate.
