Well, remember the 4:1 reverse split, so the $7.72 is based on post-split price ($1.93x4=7.72), and the $0.0035 was based on your 220,000% (7.72/2200=0.0035). If it was really $0.002 pre-split then your % was off (1.93/.002= 96,500%).
So don't act like I'm wrong because the price I used isn't the same as it was at the time. I calculated the market cap properly using 1B shares outstanding (post-split), but using your prices and the 4B OS then the market cap went from $8M to $7.7B.
