In September Rasmussen himself said D+2 to D+4 and we know from Cruising For Freedom’s calculations that he IS now using D+5. There is nothing more to debate about this subject. The math and Rasmussen’s own words tell the entire story.
Look at the chart above. It’s Rasmussen’s OWN chart. It says R +3.4 in September. It does not say D+2.
So, there is something to debate. And the calculations have no reference points or explanations, so I’m inclined to go with the guy who actually has the data set that we don’t have.
