Please make sure you do not include a comma in the name of your club/team in your online profile. Having a comma in the name of your team or club will add an extra field to your result when uploading results to USAC and this in turn will cause you to show up as DNF instead of the place you were in. The USAC results system accepts results in a comma separated field format. Having a comma in your team name causes an extra field to be added which messes up your uploaded result.
Also please make sure all the info on your profile is correct ( ie your team is the one you are currently on and your license number is correct). If you pre-reg your Info is taken from your profile Info so if there is a mistake in your profile Info this mistake will carry through to your start list Info and your results Info.
