So i did some "math" with highspeed camera and kinovea.
This guys air time was pretty accuretly 2.83 seconds,and for example henriks nosebutter trip was 2.43 seconds, and JOI 2013 a bit over sweetspot was 2.68 secs.
So atm there is not a big enough jump for quads.
( closest is maybe candid thovexs that huge hip but there was only slomos from it)
