BUT CNBC just said the hit was on the leading edge of the wing= 90 degree hit X mach 4 X 30 lbs.

Are you saying the ice/foam accelerated from a relative velocity of zero to mach 4 in a fraction of a second? I don't think so.

I had heard that the event happened 80 secs into flight at somewhere between mach 2 and 4.

I wish someone would ask Ron tomorrow whether or not freon free foam was used.
