Slightly off topic to this discussion but:
My opinion is that, this has been the issue with mining since the beginning. I can tweak the crap out of mid range hardware and get better performance then just plugging in and running much better stuff.

I am late into crypto world and I do not know that much on earlier days mining bitcoin, litecoin or dogecoin. But for now for sure, no matter how twig or optimization one can do on old PC, or decent GPU, there is
almost no chance to compete with ASIC for mining rewards. NENG is exception, CPU solo miners are fine, GPU solo miners are happy now as the base diff reset and GPU is dominatiing mining again. My NIVIDA GTX1050 is getting blocks every couple of minutes.
The idea of DynDiff variation on top of scrypt is not just to be ASIC unfriendly. The main purpose is to allow individual crypto fans to mine NENG like earlier days on BTC LTC or DOGE plus the added benefit of decentralization and security on NENG blockchain
