Update:
I'll cut to the chase

I targeted 4 keywords with 1 keyword having two pushes. These pushes used the old system not the mighty new one!
Keyword one two pushes broad match competion 1 million position before push 70 after pushes 30 with a doubling of traffic.
Keyword two one push broad match competition 285K position before push 25 after push 8.
Keyword three one push broad match competition 200K position before push 35 after push 18.
Keyword four one push broad match competition 400K position before push 28 after push 12.
All keywords are now receiving more traffic.
Bottom line:
1) It did help the ranking for all the keywords I targeted
2) I don't think 5 pushes is enough I believe if I kept targeting the root of my domain and deep linking other pages over time great results could be obtained.
3) Getting the links indexed is a problem (not just here any links using any system)
4) It would be nice if the system automatically check for broken links and we didn't have to press the fail button. I don't really have time to check them all and if a regular user I could have 100's of linkpushes to check.
5) Getting a list of URL's is great for checking if they're indexed / sending other links in but it would be nice if for each user there was a master list that was appended to after each push is completed. That way one file to submit to SB for checking links instead of having to combine them myself.
I like the system and it worked for me. My link building budget has all been used this month but I'll be subscribing early next month with the $97 package and see if I can't improve my SERPS for the above keywords.
