...squeeze post Feb 20th...

This warrant theory doesn't stand up to scrutiny (or logic). What we know for a fact is that shorts have shorted below $1 - look at Oct, Dec and Jan data (and probably Nov. too).

The Feb warrant date is likely irrelevant to shorts now (and probably always was) just as it was before with the Dec. warrants. You need to understand the psychology of a shorter. They don't short and sit for weeks waiting to cover. They trade. Short, cover, short again, cover again, etc. If the overall short position is going up it is because they expect the share trend to be down. Once the trend changes shorts will disappear quickly but at these levels there will be no squeeze.
