When I work with clients anything at .25" daily or under I attribute to evaporation and strongly discourage investing time and resources to chase it. Just not worth the $$ and hassle. Considering some areas in the country experience daily evaporation rates as high as .5" I don't professionally consider .25" daily a leak at all as that's less than 2" weekly. I'd invest that $$ into supplemental irrigation [well] if that minor seep bothers you that much. Just my advice - save your $$.
