I had intended per packet, but I see how how you might interpret that differently.  I think that you achieve the desired outcome if you make it "per connection ID".  Using per connection adds a bit of entropy that can be used to link activity across paths.  Whatever scope you choose it needs to be based on something everyone knows.  Changing daily across all connections would also likely work (and would produce some interesting stats).
