Question about burning speed

This is probably a stupid concern, however, I notice that when burning at 8x with an 851s in Nero with showtruespeed turned on, the 4x zone usually burns at 3.7x, the 6x zone at 6x and the 8x zone at 7.7x. Is this normal?


My 811s fluxuates between 7.8x and 8.1x while burning so its normal

I think the only way to really get the true burn speed, is to create a Data Disc with Nero CD/DVD Speed.
Be aware, you will waste a DVD+R disc only to get this simple information.

Before somebody asks, yes the attached pic. is of an data disc on patched FW HS0K… :cool:
