    1) Roughly how much DA/PA is passed when you 301 a clean site on say "dog training" to another clean site on "dog training"?

    2)
    How many times can you 301 redirect relevant domains to the hub or main domain? (ie: can I redirect 5 clean "dog training" domains to my main "dog training" site?)

    3) Is there diminishing returns after so may redirects to the same domain?

    1) 85% of the original authority is passed. Cutts said in a recent video that 301's have the same authority transfer dampening that the PageRank formula has, and if you read the PageRank formula, you can see that it's 15%.

    2) I've wondered this myself many times, but haven't been able to come up with an answer despite trying quite significant numbers of 301's coming in at a site

    3) I don't see how that could or would logically be the case, but again, I have no testing to support that.

    not to flame you but...

    the PR formula applies to pages while DA applies to the domain and IBL's (domain/page1 to domain) have a larger dampening factor because otherwise it would be exploited (create a 10.000 page website, link every page to main, spam).

    OP what is a clean site ? the reason I'm asking is because, while a 301 is a permanent redirect, and should pass all it's power to the target it's ultimately dependent on the site's history. 301'ing a domain that has 200 OBL's will pass less power since those OBL's will still be indexed for a long period of time and thus taken into account in algo calculations.

    I did not state that the PR formula applied to domains. I said 301's have the same authority transfer dampening that the PageRank formula has.
    My words were very different to those which you purported to reply.

    I have 1 question too..

    Let's say I have domain A and it is penalized. What will happen when i will 301 redirect it to a new fresh domain. Will the penalty pass to the fresh domain via 301 redirect?

    A penalty does indeed pass to a new domain via 301 - given time.

    It's worth noting that a penalty is usually applied to a domain for a particular keyword, so if you're doing a 301 to a new domain, the penalty will be flowing for that keyword only.

    Yes the penalty is passed and here is the source. Ouch, those algorithms bite hard.

    Here is the video, fast forward to 23 minutes and 15 seconds in:
