Here's more all-time PPV records for selected competitors. I started at Starrcade '87. I probably messed up somewhere...its just for fun, not for a grade.
Bill Goldberg 20-4-2 .769 Hulk Hogan 26-11-3 .650 Sting 53-23-6 .646 (This one really shocked me!) Bret Hart 7-3-1 .636 The Giant 15-9-1 .600 Lex Luger 33-23-5 .541 Vader 14-12-0 .538 Scott Hall 15-11-2 .536 Kevin Nash 23-18-2 .535 Randy Savage 19-16-2 .514 Ric Flair 33-31-2 .500
Maybe he's using the PWI Almanac. It handily lists the results of every PPV ever along with every Clash Of The Champions (although, sadly, not every Saturday Night's Main Event).
