Normal
I would say to the piece the chocks are on... you'll be pulling the bike down at the same general angle the forks are on... too far out you might not be getting the full tension needed to ensure a good snug fit (wiggle, straps coming untied, etc.) PLUS the straps would be in your way if needing to get something out of the caged area while the bikes are tied down. ... seriously, I know this.... I may not be the quickest bike on the track but run a close second in the "sharpest tool in the shed" category!
