Excellent article and highly practical examples! Thank you!

One question though: when having to restore to a specific point in time using STOPAT can I trust the "BackupStartDate" column returned by the following code?

RESTORE HEADERONLY FROM DISK = 'C:\BACKUP_TESTE\AdventureWorks2008R2_20110927_LOG.BAK';

That would be an easier way to identify which log backup I really need to stop at before performing the actions?
