having tested the variations in sodium sulfite levels myself ( 100gr, 80gr, 75gr, 65gr, 50gr, 35gr. ) i can say that i would never consider using 100gr of sod.sulfite per litre in a developer unless i wanted an obfuscation of sharpness. perhaps in d76, going from stock to 1:1 may give a slight increase in sharpness, in a metol only developer the decrease in sod.sulfite certainly gives more than a slight increase in sharpness. most d23 type developers require an increase in development time of about 10% per two rolls to keep development outcome consistent.
