How many minutes of audio are converted from AAC to Mp3 in the Speedmark 9 test? I cannot find the technical specifications in the article about speed testing the new Mac Pro or anywhere else for that matter. What puzzles me is that the score for the CTO iMac 27inch 2013 is 80 seconds under Speedmark 8. In the article about speed testing the new Mac Pro the number for the 27 inch CTO 2013 is 56 seconds using Speedmark 9. It is not very useful to just have a number unless you know what that number means... very confusing too.

TIA!
