At the moment, as we know a racer's LFSW pb is shown as the distance to the WR in seconds (in online racer stats). Can an option be added so that we can view the distance as a % to the WR?

Users can toggle the setting to either view the distance in seconds or as a % to WR.

Or shown both, side-by-side, as shown already in S2 hotlaps > Racer details > Distance to WR.

I would like to see date of pb as in "/w wr".

small suggestion for improvement...(although I dont know if any of devs will read this)
when you compare pbs of two drivers on lfsw what about overall difference between those times?

+1 if you mean hotlaps
It would help when comparing times for a specific car or a rank. Although you can just copy everything and paste into Excel/Calc where it's not hard to sum up a single column of differences...
