A last update of the Gridcoin mining experiment for this year. RAC seems to be going down again and I still have no clue why. I will continue gathering the data for a while but if nothing gives me a clue I need to reconsider the approach.
Purpose of the experiment
I continue this experiment because it provides interesting facts. The ones who are very involved in gridcoin know that RAC can change and is not predictable for various reasons. This experiment shows this with real life data and can help newcomers by example to see how complex gridcoin mining is and give experience users some data to look at and confirm their understanding and insights.
This data is gathered on a virtualized Microsoft Windows Server 2012 R2 Standard x64 Edition running on a Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz [Family 6 Model 45 Stepping 7] core with 4GB of RAM. The computing preferences are set to use at most 50% of the cores at 100% of the time. The project being crunched is VGTU.
Top 10 users
I'm now keeping track of the RAC of the top 10 users. It's interesting to see that these ten users together account for about 80% of the total team RAC. For this project 
Evolution
For some mysterious reason the points awarded and RAC are going down again. I'm a bit surprised to see this happening as there seems to be no relation to the other data. I was especially expecting to see some correlation with the team RAC. There is of course a slight offset due to the low pass behavior so maybe it will change over time. For the moment team RAC has remained more or less stable.
For the moment it seems GRC seems on it's way to the moon. This should really convince more people to contribute to science in this lovely way.
