I'm not sure I understand, the final min-entropy value is the *lowest* of all different estimates. Also, I'm not sure what makes you say it's an overestimate... are you simply speculating? Either way, this is quite discouraging, because this means that with that estimate, I need to gather about 25 KiB of data to meet the requirements of our DRBG.
