I am glad that the colors were consistent between the graphs so I spent less time referring to a legend.
If reports like this become regular (say, a monthly occurrence), would it be possible or feasible for the cloud providers to try to game (or optimize for) certain qualities?
It is possible - but it would be difficult to optimize for every performance characteristic because they are derived from many different benchmarks. This was a problem in the tpc-c years with database vendors optimizing specifically for a single benchmark.
