Keep in mind TF that if any of the shares were from other paid parties they would have had to have held them for 6 months prior, plus time for opinion letter, released cert, etc. before selling them.
Ironridge circumvented the holding period by having a Fair Hearing finding that immediately released them from 144 restriction.
Not to say that shares couldn't have come from 6+ month old payments, or that there haven't been new ones issued, but these would be entering the market later.
