When first recording on a new DVD

when first recording on a new DVD…is the normal mode of operation (MOO) to first check the blank DVD’s quality via something like Nero’s CD-DVD Speed?

I tried doing that and understanding the pretty colored lines…what was especially relevant to me was the disk quality rating to the right of the graphs…the Taiyo’s I got were at like 90…this is good …right?

And then…I checked the recorded DVD after it was recorded and the quality rating went down to like …20%…is this normal?..

thanks very much for your help!!!
