Blackwiggle: A good way to do it!
I´m always, and I think a lot of wipers do, keeping a piece of paper with my pb´s next to me (at least the multiplayer records ...), when racing. If beating a personal best, I more than often wake up my children, shouting Hallelujah, but at the same time I double-check with the SL-rankings build in to WO HD, before posting the results to Connovar´s more than brilliant site.
I think the results/pb´s on Connavar´s site really depends on wipers writing down records that can be certificied through SL's rankings.
