I wasn't aware that one had to charge at greater than 15 volts to get to 100%. My hydrometer would argue with that.
I have found that if I keep discharges above 85% the batts don't require the overcharge to get 100%. I will say that I have tried leaving the batts in float for weeks on end to see if they did eventually get to 100% but that never happened. That may be due to my 17" tall batts being more prone to stratification than GC's. I will say I won't chance permanent sulfation on $1100 worth of batteries just eliminate the need to use a hydrometer once a month at most.

IMHO, high Volts are for stirring FLAs; there is no reason to use high level electrolysis inducing Volts to remove sulfation.
Since when? High volts aren't needed for stirring. Regular "boost" charging voltage for a short period (15 minutes on mine) is enough. High volts is indeed required for sulfation removal. See your battery manufacturers specifications. Mine require the following:
