Explanation: delay because of wait elsewhere...

Hi, i have the following piece of code: 

MODSERIAL USB... 
...
    for (int ii = 0; ii < 10; ii++) {
      USB.printf("&%hu %hu %hu ",
		 Data[ii][0],
		 Data[ii][1],
		 Data[ii][2]);
    }
    USB.printf("\r\n");

the latter running in another loop.

If I put a wait_ms(10) *after* the last printf, then data transfer slows down because the line is not completed quickly. I would understand this if the wait is before the last printf but not if it is after that.

Any explanations?
