Deuterium removal from water


What percentage of deuterium might be removed from water after a typical electrolysis procedure? From a post on this site I read that, "In the first stage, NaOHNaOH solution (initially 0.5M0.5M) is subject to electrolysis, until only 132132 of the original volume remains. This increased the original concentration of deuterium by a factor of 1212."
This seems to be, for the electrolyzed hydrogen, an approximate 38%38% decrease from the original concentration. If we assume the original concentration was 150ppm150ppm then after the first pass, we might expect to have 93ppm93ppm in the deuterium reduced hydrogen. If my estimate is valid, may I expect that each successive pass would reduce the deuterium content by a similar percentage?
