Its a long story but my company may be doing back to back 301 redirects soon.  I thought I saw a video where MAtt Cutts was saying Google passes page rank through the first but cannot through the second redirect?  Is this true and can someone post the link to the video or source. I know a 1 to 1 redirect would be best but it may not be an option. So Page 1 redirects to PAge 2 which is itself a redirect to Page 3. Will I lose all page rank in this process?
