Also, this analysis is fundamentally flawed because mining is time-dependent. Run the miners on 6 new addresses for several days (STARTING AT THE SAME TIME) and compare those graphs. That would tell you a lot more.
The graphs are from six different miners taken at the same time. I can understand that not knowing who was mining where is a flaw in the analysis (although, why should WE be choosing where to mine @ middlecoin in the first place).
But I don't understand your reference to their timing? If the graphs are showing the same time period and you can see the begin & end situation of each miner..
You're right, under normal circumstances, *we* shouldn't have to choose where to mine, but my interpretation of what I've read in the last 20 or so pages is that h20 and co have had some growing pains (5000MHash increase last 7 days by the looks of it, for example, and steeper in previous couple of weeks I think) that have resulted in some stop-gap solutions on some servers (EU server was constantly on one coin for a while I think)...
Be interesting to see the results of another selection of miners once all the new servers are out of "beta" etc.
