I bet you'll find (on a CPU) the 64MB Scrypt takes twelve times as long as the 2MB Scrypt which takes ten times as long as the 128K Scrypt, so that when the 128K Scrypt is run 120 times interleaved with the 2MB Scrypt that is run 12 times and the 64MB Scrypt that is run once, they each take 1/3 of the time required for the overall hash.


Thanks, looking forward to it. Consider also that the clock is ticking for any GPU implementations. Should have 90% minted within a year, and 10% the next year. It would be regrettable if GPUs or ASICs were to capture the 10% and/or the 2%/year distribution, but not catastrophic.
