Yamaha CRW-F1 UX and overwrite into lead-in

Hi, I’ve just bought this burner for its high audio burning quality.
This is a model of the F1 series, more precisely the one with USB 2.0 interface (and sadly without firewire interface) with firmware 1.0g (the latest).
I have tested the read and write offsets with two reference CDs and EAC (Exact Audio Copy) offset test CD, and I found respectively +733 and +6, which should be correct having found them also in some CD offset databases.
Since the write offset is positive, I would like to know if the writer is able to overwrite into the lead-in, that is in the pregap…
Does anyone have this information?
Thanks in advance,
