Hey Eran! We actually help quite a few e-commerce sites today. To be clear, 99% of our scores are updated and ready within a second of receiving the transaction. The fact that the response to a transaction does not include this score is a design flaw, and you're not the first to bring it up. We're working on a fully revamped API that should address this, and the revamped API will be launched in the next 2-3 months.
I do remember your emails from back in the day -- will followup offline.
