Your PI Errors are peaking to 29 and hovering mostly just under 20. My experience with this media has shown that upgrading to the latest B7T9 will likely lower these PIE numbers significantly.
The yellow PIF's are peaking to a maximum of 5. This is good enough for the excellent 97% quality score. The PIF total is fairly high, though - likely mostly due to the high density clustering near the end of the burn. I'm not used to seeing this, but it might be related to the older firmware you're running, or it might just be that particular disc. In any case it's not serious since the peaks are quite low.
A very good to excellent burn that completed in 6 minutes, 40 seconds - pretty much exactly right for a 12X burn. This 8X media should burn fine at 12X.
