Also, I noticed the scrypt hash rate was 69% for 7/13/14, and 81% right now on 7/14/14. Any reason the coin switcher doesn't mine LTC to stay around 100%?
This has been discussed in this thread numerous times.
However, the key is that mining only LTC will not produce results any closer to 100% LTC, because "100% LTC" is an artificial/optimal stat.
