We explain why the standard value, determined from pion photoproduction, should not be used in conjunction with present estimates for the Delta(++) and Delta(0) masses, determined from pion-nucleon scattering. The resultant mass splittings are internally inconsistent. We also briefly comment on discrepancies found when `theoretical' and `experimental' values for the Delta masses are compared.7 pages of text. No figuresNuclear Theorytext
