After 3 months of testing and benchmarking of Bot BlackBox's GA version on yad2.co.il,

The most aggresive bot operators known, using totally dynamic IP addresses, managed to extract less than 6% of the ads updated daily.
False positiva CAPTCHA ratio was 0.36% meaning that aprox. 1 out of 300 users was displayed with a CAPTCHA though they were legitimate users.
