Don't worry about BSFC charts, just use the highest gear you can before the next gear down shows better mpg on the display.

If it's out of academic curiosity, the BSFC chart should look nearly identical to the old FA20, which should look like a 2GR-FSE but with slightly poorer low rpm efficiency. When I had a FR-S back in 2015, the mpg really tanked as you went below 2000rpm in 6th gear, which is expected because the cam profiles are high lift high duration.

The new 2.4 is paired with the same gearing AFAIK so I would expect that you want to shift slightly earlier than the 2.0 because there's more displacement.
