Many variables that can create an outside the typical V1 cut or fire.

AA 181 at ORD.....the crew followed the procedure of pitching up to attain V2 after they "lost" the #1 engine.
The plane soon departed controlled flight and crashed.

You can't blame the crew cause they simply thought the #1 engine had failed, not departed the airplane and damaged hydraulic lines in the process.

You always look like the hero when you go of the procedure reservation and win. But you become the scapegoat when you lose or even break even.

In the end of it all, percentages lend to you not having a AA181 or UA292 type scenarios.
