Honestly none of this is verifiable, no run counts, no bytes per flow, no failure rates, so I'd not treat it as real measurements. The pricing also switches quietly, since 65 rub per 1000 solves is about 0.065 each, and 20-30 rub on one failed registration only works at the 1.5 smartcaptcha rate. That makes the two orders of magnitude headline lean on the cheap solver while the failure math leans on the expensive one request.sizes() or CDP encodedDataLength are the easiest hooks, but they show what the browser saw and not what the provider billed
