I dont trust the EWBF executable anymore.

Different miner apps have different optimizations;  for a while the alexis version of ccminer was most efficient on skien, etc.

Feel free to re-add lyra2;  But before;  the pool wanted me mining lyra2; when I was making a killing off skien when I disabled it and just started mining single algos.  I didnt look at what was disabled;  but lyra2 could be enabled if you want.   

The problem with profit switching is the delta factor.  ITs only efficient/profitable if you can get algos that swap in relative amounts of time close to one another.  being on one algo for a long time, then a short on another followed by a long on the first;  nets you less profit than 1/2 on one and 1/2 on the other.   So balancing the algos for profit switching is important... but it changes as the market/miners/hashrates change.  The key is maainting a delta share input on the port.

Chasing optimal profitability is a side goal of mine now;  no longer the primary.   The simplest and best overall results is what im focusing on.  Staying on one algo that remains profitable consistently.  Lyra2 is something I would mine by itself;  because of the seemingly long possible block times with mona and vert depending on hashrates.
