Definition of ringed sideroblast

Sir, A recent article (Lee et al., 2008) defined a ring sideroblast by the presence of five or more siderotic granules encircling one-third or more of the nucleus in an iron-stained smear. This is contrast to the WHO book (Jaffe et al., 2001) which defines a ringed sideroblast as an erythroid precursor in which one-third or more of the nucleus is encircled by 10 or more siderotic granules as demonstrated in an iron-stained smear. Is there any scientific benefit in this varied approach?
