For one of my keywords, the positions are constantly changing every couple of days. Before the algo update, the page was ranked second, then moved down to 10, then 7th, and then 11th and now it settled at 7th since yesterday.
I made a change before the last change and I believe its the reason for moving up from 11th to 7th. But I am not sure about the other ones. May be it's because of the ranking changes of other sites for the keyword.
The page I was referring to is cached frequently, twice or thrice everyday since the last few months.
