I'm sorry I didn't do the digging to figure it out for you. It appears it is raising the share difficulty that saves your efficiency. I just figured you were the expert and could figure it out easier. Sorry for wasting your time. I clearly keyed in on an incorrect statement, which caused you to dismiss everything I had to say.
Sorry if I look a bit harsh, but I don't spend much time on bitcointalk right now: I have a lot of work currently and I'm slowly recovering from a broken back at the same time so if I even suspect I won't find useful information I don't dig to save time.
The meds I take may not help either: they are known to have several side effects on the mood and short-temper is one (I may be predisposed for this one...).
Raising share difficulty may not be the solution: as I wrote in the previous post the published results match a configuration with standard share difficulty.
I'm sorry to hear that. I truly wish you have a speedy recovery. Thank you for updating the guide to be less discouraging for BFL owners. P2Pool is experiencing very long block times and if BFL hardware can potentially help with that we should certainly admit it is complicated, but not actively discourage them from trying.
