I wouldn't think so. I try to keep mine to a set no more than ten most of the time and make sure they match on other KW elements. This is just my opinion and will def let the pros speak about it.

i am targeting 3% kw and it works for me

We're using according to google algorithm 2.5% to 3.5%

I often keep it between 2% ~ 5%, but deeply I think once you insert keywords in the content naturally, keywords number won't be a problem.

There is nor problem with excess of keywords.

Put them all. If they fit, they fit. Just put the keywords in there that are the real keywords for the article or site.

I keep it between 2,5%-3%. I also use LSI (Latent Semantic Indexing) keywords.

2-5 % seems standard so follow this and you should be ok by big G

I don't really get this percentage metric? when you say 2%-5% what does that literally mean?

4 to 5 % is good

I used only 2 keywords. And that is beneficial for me ...

No, I don't think no. of keywords will affect negatively but if you provide 3-5 keywords that would be more beneficial.

Good Luck

it always based on content and competition. so, most of the time 3% k is best

Make it 2.5% to 4% as per your web page.

There is no use of stuffing your post with keywords. The keyword tag is ignored by Google and other SEs like Yahoo and Bing. Only local search engines like Ask.com refers to it, so it would probably be a waste of effort.

Best keyword density to use is 1.5%- 2.5%. It is best for seo purpose.
