So you made it sounds like random values are MUCH worse than some custom values, something to be avoided at all cost.
Correct.
And now you say that some complicated method of picking custom values might be equivalent to 1 or 2 extra random bits.
I never said that. I said that random sucks and that a "complicated method" is "much better".
This is an outrageous claim.For me, this lends strong support to the advise to use true random or excellent pseudo random values, since many attempts at creating custom values (ignoring all the software engineering headaches) will inadvertantly lead to a *worse* collision probability, maximizing hamming distance being a good example.
Random values are not trivial to code.Why go through all that effort when random values, which are trivial to code, are so close to optimal???
