Basically if you connect the spokes of your link wheel then it makes it fairly obvious to google that the content is some how connected, after all that is what you want them to think.
If you do it in a blatant straight line around your wheel, especially one after the other while making them, and from one IP, and quickly (like in one day) then google will be like hmmm whats up with this.
So you need to take every step neccessary (what that means is up to you different people have different levels of paranoia / accessability to stuff) to ensure that the wheel looks like a 100% natural creation and not an artifical one. If you want them to work properly, otherwise they wont work well.
When you submit content to an article site, that content is designed to go out as duplicate content. But here is the thing about duplicate content, google dont care about it, as long as it is on a lot of different sources(IPs basically) then the content is still relevant (maybe moreso if so many people think so!). So if 1k autoblogs pick up your article from some free plugin from an article site / directory and as part of that your link gets posted by all those unique ips related to the keyword. Then you will get some link juice from which ever of those manage to get indexed and depending on the position they hold in the niche or whatever you may get some really nice juice.
Personally I perceive the reason you spin high (very high and well) for your personal small link wheels should be because the more unique each piece of content is the more google will like it on its own merit so the more juice it generates, that in conjunction with being linked to similar pieces is like WOW, and of course you dont want google to think they came from the same author (all pointless if your not masking your ip) but if at any point Google smells something fishy they will investigate the whole ring and then you could be in real trouble as all the work you put in could just be totally wasted.
You want a good piece of spyntax for when you submit to article directories because then one article (if it passes) can potentially keep getting into each major directory every week and produce untold amounts of back links for you.
Now that took a long time to write out so if it was helpful hit thanks for me
