AK at bubble, Fold or Shove (Part 2)

Pardon for the poor video quality, but basically, in the video I talk about the correct play of Hero based on the following parameter: 

Assuming that: 

1) BTN shove 50% (based on his actual play, he is shoving even 75%) of his hand

2) SB shove with A8+ (top 15.4% of his hand)

SnG Wizards still recommends a shove

And also assuming that BTN folds, and SB shove, I have to fold even AK.
