based on your table the calculated RAC for that type of processor is 49734...
If you look at the WUs of this host, there is something very fishy about it... the CPU times are waaaaaayyyy to short compared to everyone else on the list. And the host is on top and has no active WUs

the Wu versions (v0.21) seem strange, there is no v0.21 all other host are crunching on v0.20 !?

ohhhh... and it acquired all it's points on four days!!!!! thats for 127156 WUs only for this host...

this would be interesting for the gridcoin pool as well as the host is apparently mining for the pool and "stealing" MAG from everyone!
