NSA's Backdoor Key from Lotus Notes
If I got the maths right, due to the exponential relationship a 760-bit key should on average take roughly 1/256th of the time a 768-bit key takes to factor.

No, that is not how factorization scales. The time difference between a 760 and 768-bit modulus is less than a factor of 2.
