i am at work, but i can answer short form for you :)
the shorting has taken place and the mms have covered a little here and a little there so the continued shorting on higher volume will force the PPS to rise steadily, however there has been an increase in volume and usuall if the shorting is bad on those days it takes about 3 days for the mms to account for those shorted shares. the squeeze is happening now, but it gets worse for them and better for us the more time it takes when people continue to buy and not sell back.
does that make sense, major break in pps probably anytime between right now and mond tues wed of next week, so stay patient, you are in this at the beginning, which is excellent for you! buy and hold
