For being supposed mathematicians, chartniggers really aren't that elaborate in their charts...
Is Line 1 vs Line 3 - Sig vs No Sig? If not, what's the difference? Both say Cia R1 + Rover.
Is Line 6 Cart - Shokie - Rover with Cart Sig or without? Is Shokie R1 or R0???
No wonder IWTL glossed over this chart for a combined total of 5 seconds saying "HUUUUGE 20% loss!!!".

Does anyone have a chart for Carlotta with Zhezhi vs Non-Zhezhi? I can't seem to find one.
