IMHO, they sell every last share that they file 144s for. Don't forget that they get shares via options as well as conversion of debt/salaries. Most if not all of those shares that they receive are subject to 144 rules which means that they get sold over 10 or 15 years.
LTC... I don't blame CDIK for 1 second that they sell and hold to retain ownership and control until they can get this ultralight off the ground. It is exactly what I would do.
