Has the advice at the beginning of this thread been updated to take into account current difficulty and network hashing power, and newer hardware?

Also, what is best practice for tacking "/2000+512" or whatever onto the end of your BTC address to set a higher share quality and manual difficulty?

I'm finding myself on a good network connection with low latency on good hardware and I suddenly have 2TH of miners on my node, but hardly anybody is getting shares.

Thanks In Advance
