The joke is your inability to interpret a technical chart.  The 'per TH/s' is just a scaling factor.  If it makes you happier, lop three zeroes off the y-axis labels and read it as 'per GH/s.'  If you understand what you're looking at, it says the same thing you ranted at Sandal_Hat about.

Do the mods actually buy your 'just for shock value' nonsense?
