Commenting out a print slows my code?

I couldn't get the code to compile with the stop watch. So instead I removed that and used time. In this case I get user times between .150 and .200 approximately. Maybe with the print statement your program is given higher priority than without, that would mean the operating system would let your application run longer or more frequently than other programs (don't remember if one or both of those is changed).
