> In 2013, we announced an early success of RCN: its ability to break text-based CAPTCHAs like those illustrated below (left column). With one model, we achieve an accuracy rate of 66.6% on reCAPTCHAs, 64.4% on BotDetect, 57.4% on Yahoo, and 57.1% on PayPal, all significantly above the 1% rate at which CAPTCHAs are considered ineffective (see [4] for more details). When we optimize a single model for a specific style, we can achieve up to 90% accuracy.

66% with reCaptcha and up to 90% when optimised is much higher than what I can achieve with my actual brain. Maybe I should consider using a neural network to answer those, it happens quite frequently that I need 2-3 rounds to get through reCaptcha.
