What are you questioning? My math said imun would fall from the 30 cent level to 14 cents (adjusted for the r/s, that equals $30 to $14). The only error in my math was that I underestimated the damage that would be caused by the r/s as the share price has gone much lower than $14.
The opinion was stated when imun was near 30 cents and others were predicting it would go to .16 to .24 - none of that "after the fact", hindsight, Monday morning quarterbacking stuff.
I'm SURE that anyone who acted on that opinion is quite happy with my math.
