Mark, FWIW, my previous rebs were washed pretty frequently - dunking x3 days, then every other day for a while, then 3x week. I did develop slip skin.
This time, I'm trying to encourage a bit more of a delicate dance among Time, linens, and PC. I washed these, as you did, for 3 days worth of dunking, then just a few more days of every other day. I then left them alone; PC matting came on, left it be for about 8 days, then washed again. Since then, I've really just watched them, and washed them very infrequently - trying to encourage linens development, but not
too much, too fast. I'm a month in, and unlike my previous batches, no slip skin, though there is good linens development throughout. I plan on doing no further washing, and am hoping for latter-stage dusting of geo, as Yoav has mentioned and as I can see, from many reb pics in the books.
I broke into one of the wheels, just to see what I am getting, after a mere month (the book French Cheeses mentions anywhere from 2 weeks to a month affinage - seems crazy, to me, but that's what they indicate).
Very, very pleased, at this point. Pretty wonderful result, knock on wood. Rich taste, great balance of linens, mold, salt, butteriness. The paste is too firm, but I expected that. If at 2 months, it's still not quite that soft, pliant paste I'm shooting for, I'll likely move to 5x multiplier from 4.5.
Anyway, FYI as an experience point, if it's helpful.
