If possible, could you not give out the actual values for enjoyment? By that I mean, could you just give out a broad "she likes X", "she loves Y", "doing Z makes her feel yucky inside" - as opposed to just tossing out the numbers? I feel that not knowing the specific values for enjoyment makes the game a little harder, and a little more... not 'realistic', maybe 'immersive'? I dunno, but I personally like not knowing.
EDIT: on second thought, I'd just prefer not to know at all. Partially, this is because I think necno intended to keep it secret-secret, but mostly because I truly think the game is better when you don't know. Why should the player know the exact value of every stat, for every girl? There's no reason to justify that... the more I ponder about it, the more I start to suspect we almost know too much already. I would kind of like to take even the stats that are given out now and reduce them to estimates, like I suggested above - instead of knowing one girl has a BSDM value of 50, and another a value of 80, instead they would be "competent" and "supurb", instead.
