You are counting trading days from Sept 1.. I am from Oct 2, when the warrants were finally finished.. We don't know how many other warrants were held by S/L and were converted/sold in the traditional manner b/t Sept 1 & Oct 2 (besides that 5M).. and if therefore his retail shares count remained constant or not... If those were indeed the only warrants Swartz held at that time then the counting should in fact be started at Sept 1 as you are implementing.
I will have to do a bit more DD, but have a Saturday to try to enjoy... you do the same Dys
thanks again & regards
