Yes, I heard about this tragedy and actually referred to it on my initial post. From what I heard, he is quite experience and done track as well. No one knows how fast he was going, could be double or triple posted yellow or it could be at spee# limit or maybe just a little over, who knows. However, some had mentioned they had fallen quite unexpectedly with just a little over posted.
Thanks for everyone's feedback, despite being more comfortable going much faster than posted ramp speed, I think I will take a more prudent approach and go in at posted instead of going over. None of my riding buddies fell from ramping and their entry speed is much higher but that doesn't mean it will not happen eventually.
What prompted my post is that one guy said as long as you keep it below 3x posted and you are comfortable with the speed that should be fine. But even if you can do 4 or 5 x the posted confidently, that would be too dangerous according to him. Again, this guy hasn't gone down yet, may have a different view when he does.
