Keep +in mind however that your CPU is busy doing many things simoultaneously +\, so even though a process might take 5 minutes to complete \, your +CPU does not pay full attention to that process for the entire 5 minutes. +Instead \, it simply begins the process \, then refers back to that +process from time to time until the it is complete. In other cases +\, your CPU might require a full 5 minutes while Pd might report that +merely a few milliseconds have passed.
