Using 18% dilution in total volume puts us on mark of the 2 known 504 points, March 5th @ $367,000, and March 21st @ $436,259.
Continuing with this rate of dilution we are currently at ~$830k.
Now, at current volume levels, we're only getting about $5k a day, so we need to be hoping for another peak before ridding ourselves of this thing.
All just a rough, crude calculation of course, but right now it's the best I can come up with.
