This number seems a bit large.
But the other numbers could easily be a precision effect considering the 
RMSD is 4000.
You can check the results by manualy calculating the total average
from the averages g_energy reports for each single energy file
(of course taking into account different weights if the run times are 

I just recalled that the RMSD of concatenated files is not correct
as eneconv -h will also tell you.
But the averages should be correct.
