Webmaster tools keyword positions not accurate at all?

Ok, for one of my keywords its giving that im 11th position on average in webmaster tools.
But when searching google.com from another browser, without logging in, im no where to be found on the first 10 pages.

And that seems to be the case for a lot other keywords.

Huh?

 

i found that goole learns from you so if you keep clicking your links it will promote your result, this info then gets sent to webmaster tools. install a clean browser and use that to do your site searchs and dont click you site for correct results or get your self a copy of alex's software ibp for your searchs

 

i did the check from a clean browser as i said

the rest i didnt understand :>

 

post a link to your site and ill run a test on it for you if you wont

 

thanks but that's not the point...

 

It seems that the keyword ranking results being displayed in Google webmaster tools is the previous days result not the present results.
