I've been trying this out for the past 3-4 weeks, since not long after the first post.
Although I cant offer quantitative data, the qualitative data is offering strong support for this method.
I keep a razor on the sink which I use regularly, and one in the tub in case I find a spot I missed. I normally throw out the one at the sink in a week or two, depending on how much I'm home, and toss the one in the tub maybe once a month. Once the things start to snag or scrape, gimme a new one.
The shave offered by the razors used with this method have noticeably less drag. I dont bleed anywhere near as much as I used to!
In all honesty, the method seems to extend the useful life of the razor, reduce discomfort, and gets the job done.
