Lol, there is no way to exaggerate Simone's greatness and she should have won by more in my opinion because I for one think the separation in vault E score was absurd. That vault is a point better than most other vault in the competition as far as timing, form, raw power (height and distance) her technique is perfect. Yet it scored like 2-5 tenths higher than other amanars, eh. Even with landing deductions (no one else stuck amanars anyway) that vault in my opinion is at least 5 tenths over Aly (leg sep, bent knees, technique/timing on entry and block technique) who is the closest...no other vault was close and should have been hit for amplitude, timing, block, form. No disrespect to Aly, she is a great vaulter too. But Simone is more than two tenths better than her on that vault.
Under any system we've never had an Olympics where someone could have FALLEN and still won. Sure the margins are bigger now, but you also have to do a lot of things you didn't have to (corner rules before tumbling, no step out after tumbling, release heavy bars which is more risky). But I agree you can't compare generations so much, I fully believe we've had Olympic gymnasts who could have done WAY WAY more in the equipment and resources we have today. But still, we've never had anyone who was this dominant over their field of peers except maybe Nadia.
