Two cooling methods in one design
The 2009 comparison lists both train-draft-cooled TCI100/WPC203 converters and forced-air boiling-cooled TCI3/WPC202 equipment. A single cooling label would hide this distinction.

Details from the literature
What does 1C4M mean?
In the N700 main-circuit example, one inverter controls four traction motors. The notation describes how the electrical drive is grouped. It does not count the motors in the whole train. Look at the complete formation before comparing total output.

Inside the train
JR Central lists rotating, reclining seats for its Tōkaidō–San’yō N700 and N700A. Green Car uses the coordinated-recline comfort seat. An N700 label alone does not identify the eight-car San’yō–Kyūshū interior.
