Default Hyper Ground System instalation

I am getting ready to install a Hyper Ground System on my WRX but I had a few questions. The recommended setup is to create a daisy chain where each ground wire connects directly to the other, eventually leading to the Neg. battery post. I originally had the "grounding mod" on my car but that was set up with each wire running from one section to the next without actually connecting each wire to the next. I was wondering if anyone had installed the setup in the correct way, and could tell me the what the best connection points are? The grounding mod helped a little, reducing the feel of 'wind-up' that is often refereed to as "hesitation" and I am hoping the Hyper Ground System will come close to eliminating it. I read a dyno test in one of the tuner mags that claimed it actually increased hp, but as the mag said the gains differed depending on where the wires were placed (and it took a dyno to do find out where to place them) I think it would be hard for me to find the best set up. I obviously can't justify dyno time for a 2-5 hp increase, how ever I think it would be helpful to many if some one did, because of the popularity of the generic grounding mod. This is just wishful thinking about the dyno as I'm sure no one has done it or has any realistic intention of doing it, but any advice about optimal placement, including knowledgeable speculation will be appreciated. From searching the forums I understand that grounding both sides of the intake manifold is important but as I am not to bright on the subject does this mean front and rear or left and right? I personally did not buy the kit for hp but I can't shake the idea I might be missing out on some, every little bit helps. Mostly I am just looking to find the best places to attach the wires to so I can get the most benefit (what ever shape that benefit takes). thanks

Sun Auto has their Cyber Speed version of Hyper Ground and Hyper Voltage, custom made to fit the WRX with a specific bracket, exact length wires, specified mounting points, etc. They are available through southcoast performance
Tested in DSport on a new STI with +6 or 7 hp! (may 05)

I used the Sun HGS for the method linked above via daisy chaining rather than splitting off from 1 master line. It worked great.
