Saved translation editing economics

Read the explanation

The first saved sentence assumes five point three editing hours per thousand words and five dollars per hour. Multiplication gives twenty-six dollars fifty editing labor, compared with entered twenty-dollar direct human translation. Bars share zero at twenty pixels per dollar. Historical anecdotes, ratings and rates are representative source fixtures, not verified archival evidence. Twelve dollars machine cost adds to twenty-six fifty editing labor, totaling thirty-eight fifty per thousand words. Bars show the two components at twenty pixels per dollar. The sum explains why a low computing charge need not imply lower overall translation cost when substantial editing is assumed. Modeled machine-plus-editing total thirty-eight fifty exceeds direct human cost twenty by eighteen fifty, or ninety-two point five percent. Bars share zero at fifteen pixels per dollar. The program calls that scenario unviable; this follows its chosen inputs and is not a universal judgment about contemporary translation systems. Full native export/reset and responsive allocation are checked.
