Alright, Lite-On scans. A PIF 2 max. scan is a typical good burn on a Lite-On, somewhat similar to what a PIF 8 max. would be on a BenQ. This is due to the fact that the BenQ reports PIF values per 8ECC blocks, whereas the Lite-On does so per 1ECC block, so naturally BenQ values will be higher. And an "in spec" Lite-On scan should not exceed PIF 4 (anything higher and you'll see the colour of the spikes change from green to yellow to red in the graph).

Scan speed. 4X CLV is generally considered as the standard for Lite-On A1/A4 drives (like your 20A1S) here at CDF. This stems from the fact that, depending on the individual drive and media used, many A1 drives (and to a lesser extent A4 also) will show abnormally high PIFs at the start of an 8X scan. That said, DQ scanning isn't an exact science and anyone is free to scan as they see fit to obtain the desired information (even at 16X).

P.S. Have you noticed yet that CDSpeed starts up much faster with "Windows Version" set to Windows 98 in winecfg?
