Guys just copy paste the N scrypt from vertcoin even their schedule. They are 100% focus on avoiding asics, yes is less ecological and requires some tweaking but it should be a once in a lifetime fork. Then we can focus our minds and resources into science.
Vertcoin is just an adapted scrypt algo, really not 'ASIC resistant', the multiple hash of X11 or Quark algo would take much more effort to build an ASIC against ...
Chaining NIST approved algos is in no way asic resistance, theres not a single one which is memory hard - its just cheap to put that on a chip...
If you want to know the reason why x11 mining takes less power, its simple - the miner is totally unoptimized.
There is also a big disadvantage with that, cpu mining is nearly as fast as gpu mining...that means, its ideal for beeing mined on botnets - thats something you really dont want.
I dont really find that it matters if it is indeed optimized or not. If it was optimized it would mean generally speaking a same perentage increase of hash for every miner, meaning they still get the same proportional reward. Can you explain what you mean by cpu being as fast as gpu?
