I wasn't talking about the FZR pace but the XRR and FXR pace. As a general rule i say the fastest lap on r3 with low fuel would be about 1 second off the WR, give or take 2/3 tenths. The XRR record is 46.9 so at least a mid 48 for the XRR is imo reasonable, same with the FXR, it's a 47.4 so again mid 48s, very reasonable imo.
Also count in the fact the FXR and XRR will save about 3/4 seconds each pit stop due to fuel which will multiply over a 16 hr race to over a minute
