You missed my point.  Evil-Knievel created a weak RNG on purpose to show that if you use his totally weak RNG then he can recover the private key.

If you know that all the private keys you are generating are very near certain points then of course you can find them.  He is cheating.

In other words Evil-Knievel has done nothing and found nothing.

Here is the RNG he is using:

Code:
Pick a random N, [128, 255].
Pick a random M, [1, 20000000].
Spit out 2**N - M as a private key.

That is NOT a secure random number generator - it is barely random at all.
