Allen also made the top-five in all four major tournaments in 2004–05, the only time that had been accomplished since the ABC/USBC Masters became an official PBA event in 1998.

In the 2009 Pepsi Red, White and Blue Open, Allen set a PBA record for total pinfall in a 48-game qualifying block, both scratch (11,888) and with bonus pins (12,308).
