@SuzukaStar is truly THE test piloto.  Once again (as Suzuka) I have plotted his data, seconds versus PP. And a smaller subset, the 490-510 PP bracket.  Of course there are the outliers, GSX, a Tesla, a Merc SL, but you'll see how the majority of the other cars fall within the low and high bands (1 std deviation)
108.880         490  SRT Challenger SRT8 '08
104.754         490  BMW M3 CSL '03 
110.158         492  Tesla Model S Signature Performance '12
102.876         492  Suzuki GSX R/4 '01 
104.329         496  Ferrari 365 GTB4 '71 
109.288         498  SRT Charger SRT8 '11
105.307         498  Chevrolet Camaro SS '10
108.476        499  Mercedes Benz C 63 AMG '08
107.595        501  Ford Mustang Boss 302 '13
106.238        502  Amuse Nismo 380RS Super Leggera
107.216        505  Aston Martin DB9 Coupe '06
105.849        505  Chevrolet Corvette Z06 (C5) '04
106.671        506  Renault Sport R5 Turbo Rallye '85
109.504        509  Mercedes Benz SL 55 AMG (R230) '02
106.925        509  Lexus IS F '07 
105.336        510  BMW M4 Coupe
Thst Ferrari 365 seems to be a sleeper.
Surely anyone can see the well-defined corelation between PP And lap times.
