Hey Alex!

With the introduction of iterations in iostat and vmstat (5 runs, 2 seconds apart), the interval calculation is no longer accurate. Line 39 can be updated to something like the following to correct that:

let TIME-=$(($INTERVAL+16))

Hi Cody,

Thanks for noting that! I've made the changes you suggested.

Kind regards,
Alex.
