No, I'm not asking how much of a change the Isonoids would need to impact Earth.
I'm asking how much DID the course change from the NASA forcasted path they predicted after Ison passed Mars, when they updated it, but before it passed the Sun?
Remember
2013.12.06 Gary V said "Given its "traumatic" disintegration when it was near the sun, and the possibility that only a tiny piece (or pieces) was left, the orbit must have been changed."
How much did it change?
