No offense taken. I attempted to do precisely that but found the exercise difficult given the method of presentation. I saw no harm in simply asking and appreciate the answer in that the arbitrage can provide useful information given there should be a direct correlation.
Because I felt bad, I actually looked into it. In a highly un scientific way I took both charts, put them on the exact same time scale (the full life of AM100) fucked around in photoshop and came out with this in 20 seconds.

It seems like people could care less about that fee now, as the difference between the prices is so little it is hardly there... in fact for some points in time fractional shares are above full shares.
in edit: I see there's a whale
