Could you please confirm Accuracy of Full-Scale Error of AD5422 when current output.

In case of External Rset, datasheet shows +-0.15% FSR. Here if use external resistor with +-0.1% accuracy, does final accuracy become to be +-0.25(=0.15+0.1) %FSR ? And it is worse than the case of Internal Rset which shows +-0.2%FSR on datasheet ?
