We're about to enter an incubator program (Startup Chile) and I have no idea what their funding rate is. I'm guessing that less than %50 of the startups get funded, certainly by VCs, within 6 months, mainly because Startup Chile supports very early stage companies.
I think the number funded is much, much less than that, and not just because they are funding early stage companies: http://hervalicio.us/post/14915671294/on-startup-chile
Good luck - I hope your experience is better than that.
