I get you cannot tell for sure which inputs have been used to create the outputs (the same principle like a mixer). So
G could have been created by sending
C or any other mix out of
A, B, C
But isn't it more probable that an odd amount of the same size output/input is a full transaction?
Maybe I also have a misunderstanding what can be seen on the blockchain but there must be inputs/outputs in order to verify that the sum of inputs equals the sum of outputs in a block.
