I think you have an excellent strategy and approach, very well thought out. I'd like to think I'd follow a similar line if I were fortunate enough to have more time to spend in CR on a regular if not permanent or semi-permanent basis ... and hopefully meet with a similar level of success (note the use of the elipsis to indicate a deliberate pause in thought rather than just a more routine end of sentence

). It may be hard for more casual visitors (or ADHD guys like Crazyhorse) to imagine ever getting bored with the P4P scene, but I could certainly see why that could get a bit old and routine after you've been there a while.
I agree with MH that you need to emphasize that your approach and success rate really could only practically apply to someone else in CR on a permanent or at least semi-permanent basis like yourself rather than to the much less frequent visitor that probably makes up the vast majority of this board. But I actually appreciate the scorecarding. OK, a one week every few months guy would probably never be able to match those numbers, but it does at least give them an idea of what sort of success rate they MIGHT acheive if they were there more regularly. The problems I see with your numbers are twofold. One, obviously, they're really just for you. Someone else might get similar results but there are so many variables that could impact those results such as physical fitness, attractiveness and age (you say you're relatively middle of the road on that so that could mean possibly radically different results in either direction depending on the guy and where he fell on those measures), spanish language ability and personal charm, dancing skills, pre-selectivity (you say these gals are all hot, but that is subjective and if a guy always shoots higher or even if he shoots lower as well, it could lead to different success rates) as well as many other factors. The second problem with your scorecard is that you neglected to include the ultimate measure - "true love found = zero so far."
And if I were to find one possible fault in your overall approach that might be it. It seems like you are coming at this from a very grounded perspective. You say you're not one to be caught up in emotions and are not delusional, which is good, but when you say "Yet to find my true love soul mate" it suggests to me that you at least hold out that hope. And I'm not saying that is necessarily bad. I'm only saying, being the cynic that I am, that is probably not too likely no matter how you try to improve the odds and that, if it were me, I'd look at that prospect as just a potential BONUS that I wouldn't really count on happening that much. If it does happen -great! If not, well at least you're having a fun and mutually beneficial realtionship with someone you like, so be happy with that.
There are 3 things I really like about your approach.
1) I think its really wise that you're opening yourself up to at least somewhat older chicas. Practically speaking the younger 20-ish ones may be super hot but it is probably far less likely they'll have even a modicum of the maturity you'd need for any sustained non-purely sexual relationship. Unfortunately, while the 30-ish ones might be better in that regard, as you have found when dealing with these relatively uneducated ticas, even there they may not measure up to our ideal standards. And short of going with ticas much closer to our own age (who STILL may not meet our intellectual needs and whose physical attractiveness is usually beginning to slip just like ours), even the 30-somethings represent a fairly sizable age difference for guys in their 50's and beyond. I guess the real trick will be in finding the right balance between still having enough of their youthful beauty and sexual appeal left on the one hand and having enough of the emotional maturity that SOMETIMES comes with age on the other. And I'm not 100% sure that can even be done.
2) You seem to wisely recognize that, while also treating them nice is very important, the financial stability we can offer is really our primary drawing card when we're talking about relationships with such much younger chicas AND you're wisely setting clear limits on how much you're willing to spend, how you deal with that in general and are considering your possible financial risks. BTW, I realize the 9 you've scored with you've bedded multiple times, but as long as you're keeping statistics I'd be curious to know your financial scorecard in terms of how much you've spent in total in terms of dance lessons, expenses in the clubs on all the chicas including the dead ends, expenses you've paid on dates (do you take them to fancy and expensive places or to the more down to earth modestly priced type ones), voluntarily buying them gifts (as opposed to the RFM's initiated by them which you turn down). Then divide that total amount by the number of nights you've bedded them. I realize that there is also a qualitative difference in those encounters as well as probably an enjoyment factor even when you go out dancing and don't get any numbers or on dates where you don't score, but it would at least give us some comparative financial measure vs. the more traditional P4P that the rest of us primarily engage in while in CR.
3) You're taking the potential paternity issue very seriously as well. I realize that you "might be open" to having a couple of K*ds of your own, but presumably that would ONLY be with a chica you were reasonably certain of having a sustained long-term relationship with. Right now you're still searching and you may never find that permanent chica. I think you should REALLY ask yourself do you really WANT fresh K*ds at this stage in your life (not just "open to it") because despite your best efforts you may find that one of the chicas you're seeing becomes pregnant and it very well might not be the one you'd want to enter into such a long term commitment with. It's not unheard for some chicas to do such things as poke pinholes in condoms and do other tricks to lock in a potentially valuable meal ticket. If you really could go either way about ever having your own K*ds, then you might be better off to prevent any unplanned (by you) pregnancy by getting yourself snipped. That takes all the guesswork out of the equation, puts the worries out of the back of your mind, makes you immune to any of her potential tricks, puts you in complete control rather than her and, assuming she's a non-pro that you're reasonably certain isn't sleeping around, enables you to do away with the condoms altogether making the sex all that much better.
