Not at all. I'm saying is that, if you use all three chainrings, the ideal shift points are where my graph shows them to be.
Starting in the lowest gear:
Small chainring, use three sprockets starting with largest
Shift to middle chainring, then go three more sprockets
Shift to large chainring, then go the last three sprockets to the smallest


This yields 11 unique gear ratios.


Of course you can use other combinations if that pleases you but the chainline will not be as straight and you'll probably get some overlap. Around the city, I settle mostly in the middle chainring and do most shifting at the rear. Whether or not that actually matters I have no idea and I'm not too concerned about a 'perfect' chainline or maximum efficiency.
