Where the requirement is 67%, does the FI choose which 67%? If so, does this raise a risk they will cherry pick the data inputs that make them look best?

Yes, FIs have flexibility in choosing which 67%. This is intended to provide some flexibility especially for sectors that are not fossil fuel. The targets are based on percentage reduction or %companies engaged or portfolio temperature score alignment, so the risk of helping FIs look better is limited from this aspect.
