PIE / PIF interpetation
The fewer errors there are, the lower the highest error value is and the more evenly the errors are distributed, the better is the result. A few isolated PIF spikes higher than 4 are usually no problem and can be ignored, however, good PIE results do not even come close to 280.
Here we see a good scan	This one is not so good. many errors from the middle to the end Writing Speed should be reduced.
Beta / Jitter interpetation
A Beta scan (red) result is good if there are no stair-case shaped jumps. Also, the beta graph should stay between -5% and +15% (for DVDs) and between -8% and +8% for CDs. However, staircase like jumps are more problematic than beta values outside the given range. Jitter Scan (green) should also show no stair cases.
This one is getting better and better	A nightmare
TA interpetation
A TA test result is better when the peaks are more clearly seperated from each other. Also, the peaks should have their maximum each one on its black line. However, this is not yet automaticall.
