A small comment here as I was unable to access your google drive file. Tuning is not so universal, my own efforts with old AMD cards and Cryptonight lead to different results -  maximum hashrate was strictly with maximum core. So at least you should have some notes of applicable chipsets|GPU. In my case Cayman GPU was pushed from 830 to 950 Mh core, 930 was stable but with huge power consumption and critical temperatures so I limited it to 890. Memory tuning have nearly zero effect so I stick with basic frequency. I was aware that Cryptonight is "memory intensive" so I double check my results :-) Maybe it will be a hint for non-standart GPU users to check where is your bottleneck.
