Ok, thanks guys for the fast reply.

B.T. Coin: I am using those in my batch files and found a really good program (manager) called Awesome Miner that uses them too.
Wolf0: Wow you are one of the developers I see who makes modded kernels. I am honored by your reply. Please elaborate on how the stats work and count.

AwesomeMiner downloads a fresh miner (today it's saying it is version 4.2.2) None of the v5 devel miners worked until I upgraded the buffer to 1G for the GPU portion of my AMD A8 APU. I am giving about 225Khash to waffle pool right now, but they don't accept very many of my shares. Other pools are much more accepting of my work. NiceHash is in close to the same range as Waffle when it comes to work accepted. XPool and Ghash.io accept way more of my shares then these new-to-me pools do, but these new pools are multi-algorithm. Does that make a difference? Should I try NiceHash's non-switching ports? will that make a difference in the acceptance rate?

What factors affect the stale and rejected rates and how do I increase WU, which I suspect is Work Utilization. Is there a glossary for all these terms, a WikiPedia article or something?
