Have you seen an increase in your Rankings after improving your TTFB rate?

After reading the Post by ZOOMPF http://a-moz.groupbuyseo.org/blog/improving-search-rank-by-optimizing-your-time-to-first-byte I was wondering if any of you have optimized your TTFB and noticed improvements in rankings.  Have you optimized and not noticed any differences?

The best post/information I came across was what Geoff has written here: http://a-moz.groupbuyseo.org/blog/site-speed-are-you-fast-does-it-matter

Under How important is Site Speed? In two words summary of Google and Matt Cutts reply is that its a factor, but a very small factor of the many factors involved in rankings.

I am also interested in this question as much as you are, but in my efforts I haven't seen a noticeable change in rankings just solely related to speed, this includes TTFB and other speed improvements.

Having said that. TTFB and overall speed optimization is important in conversions on your site and ultimately in providing better user experience, which is always really important.

This leads to another question that you can ask, did improving TTFB improve conversions, or lower bounce rate, etc? This also is a great question, that I am curious in as well.  From my end I did not have a client that was that worried, or had a horrable TTFB that I could measure and notice a difference, but very interested if someone had this effect

Hope this helps
