Well yours look very successful to me, Pete!
I put mine in the refrigerator (38 degrees) as soon as it had full mold coverage (in my case, day 5 or 6). I have read about many who leave in the cave to age and many who choose the colder fridge environment. My recipe called for the fridge, so I went that route. It is supposed to take 5 weeks after that to mature, so we'll see.
I'll start taking a look at it next week to see if it seems to be softening at all. For the moment I just flip it daily.
Good luck and keep us posted :-)!
