Sfp, Disappointing if you are making the same mistake as many, by
using a statistical estimate of
precision as the
total error.
Meaning, that if he were on the Yucatán Peninsula, say 65Mya, a few hours before you know what hit right aboot there, he would claim that 65Myr in to the future (e. g. December 21, 2012AD), the Solar System would be in
total chaos, simply bescuse that's when his theory / numerical model goes to the crapper (he's doing these calculations at 80 - bit extended
precision BTW, but I really don't know why he's not
using quad (128 - bit)
precision).
