Article spinning question - please help

Whats minimum % of uniqueness should a spun article be for tier 1 links?

I have spun an article on sentence/word level and using the bulk spin tool of chimp rewriter, the minimum is around 65% with a maximum of 80%. You guys think this should be ok? (btw, I have not spun any pics/videos into the article yet)

Those % sound like an ok starting point, the higher the uniqueness the better, if you are adding unique images, pics, vids, meta, page layout this will also help. Alot also depends on the use of the content, for tier one alot of people use 100% unique custom content, for levels 2-3 it goes down to say 80% and 65%

60%-80% would be fine as long as the copy will be readable. There are some spinned contents that is not readable which will not help your rankings at all.

thanks for the replies guys. I have done more sentence rewrites and getting an avg. of 85% now. Just gotta input images and videos nw then blast away (btw, the articles make 100% sense to human readers)
