I think you need some serious help in learning the difference between 2^112
and 112, and that you really don't seem to have much grasp of the entire
concept. 112 bits of entropy is 112 bits of entropy, not 76 bits of entropy,
27 bits of bull, 7 bits of cocaine, and a little bit of alcohol, and the 224
bits of ECC is approximate anyway, as you noted the time units are
inconsistent. Basically just stop fiddling around trying to convince
yourself you need less than you do, and locate 112 bits of apparent entropy,
anything else and you're into the world of trying to prove equivalence
between entropy and work which work in physics but doesn't work in
computation because next year the work level will be different and you'll
have to redo all your figures.
