It's absolutely ridiculous to worry about the security difference between 9.966 bits of entropy vs. 9.964 bits of entropy.
You are also assuming the attacker is optimal. If the attacker has a bias that will reliably exist, and you counter-bias your generator, you can get better than 999/1000 odds against the average attacker.
