TOTAL 3.26m 0.3m XT trades during this time
Lets say 3 million since the top 20 update

Can understand why they don't do the buyback for Camac but just have it in the holster, if you do a script and cash deal with someone, likely discounting your shares as part of the deal, and then someone (Camac) just dump them all are you going to be nice about it or just let them go to shareholders who are willing to pay market price. No brainer to me, buyback will get used if the SP tanks badly or after Camac are out, my opinion only
