To get 50 hours of CPU time in 72 hours of real time would require a
process to use an average of 70% CPU usage during the entire 72 hours. 
However, interestingly enough, using only 1.15% CPU averaged over 72
hours, the process should accumulate 50 /minutes/ of CPU time.

Are you sure you read the ps output properly?
