For checking exactly what the ASUS DRW 1608P reports, we used three different media, burned with other writers. The three media have been measured with the well known AudioDev SA300 DVD CATS system at 1X. We used the latest version of CDSpeed, with a special switch to turn this function on. Please note that the posted results are only valid for the specific tested ASUS drive. Using other drives, even another ASUS DRW 1608P can produce totally different results. Be aware!

• Test Disc #1

In the case of PI sum the trend lines are similar but the values are very different. On the other hand, with PIF both trend lines and values are similar.

• Test Disc #2

For sum, the trend lines is the only thing they have in common, while in the PIF graph, there is a small resemblence not only between the trend lines, but to the values too.

• Test Disc #3

In this case, we have completely different trend lines and values for both PI sum and PIF graphs.
