Jeff, Dave.

After Jeff installed the new h1susetmx model I plotted its cpu usage histogram and compared this with the previous version. Plotted is the histogram of the number of cycles of the 16384 cycles in one second against the cpu processing time for that cycle (in microseconds, 60us being the max). Most cycles were taking 45uS and are now taking 36uS. There are alway a few outliers at the beginning of the second when certain housekeeping activities are process. These usually take an extra 6uS, so the CPU max was 52uS and is now 41us.
