Which IVF success rate data is more accurate?

When looking at IVF success rates, you have two data sources available in the US.
1. SART: The Society for Assisted Reproductive Technology reports the most recent IVF success rates of their member fertility clinics. Their annual report is entitled "IVF Success Rate Reports" and is available at http://www.sart.org. Fertility clinics who are current SART members are required to follow SART guidelines, which includes the reporting of IVF success rates. However, not every clinic is a member and not every member submits their data to SART. The SART data is therefore not as complete.
