I have read it can take anywhere from 7-10 or up to 50 laps with water, depending on your coticule. Watch the video of that lady at the Dovo factory honing new razors, she really whips that blade around the stone and makes a ton of passes. You might try just giving the edge a slight dusting on balsa.Apparently, I made too much slurry that dulled the edge, and didn't do enough passes later on to bring it back.
