My search hits are back again!

Remember this post http://br0sk.blogspot.co.uk/2013/01/how-i-lost-85-of-my-search-hits-over.html. It describes how I lost 85% of my search hits to this blog. On the 6th of March for some magical reason I now rank better in Google and the result took a leap back up to the same level as before the downgrade.
To me this is very strange I haven't made any changes or removed any contents. I have heard a rumour that there is a new Panda release coming up http://searchengineland.com/googles-matt-cutts-on-upcoming-penguin-panda-link-networks-updates-151273 maybe the sudden increase in searches hitting the blog has something with that to do.
