Na that's fine. You dont need to be anal about checking the graph but if you think your connection is playing up or you start getting random disconnects then you need to check the graph. You are looking for fat red lines top to bottom.

Do post them again later today when it's settled down. The Mini-slot size is all over the place and one of the power levels (US-1) looks like its moving around.

Re: 4 upstream channel bonding - post here
 

don't worry about it, qam64 is only 50% faster than qam16 so you aren't missing out on much, especially if you haven't got any speed probs anyway.
