This might be a strange question.
I want to compare something happening at the moment with another thing done a little earlier, and again with something done even earlier, etc.
So, I guess I should use the terms "current", "previously". Is this correct?
As my original post might be confused the reader, I am adding my problematic sentence as;
When a mis-match arises, then the previously fixed edge should be fixed again with respect to the current edge and the edge before that with respect to the previous edge etc.
My confusion is how to mention the one before previous value, and the two before previous value, and so on.... any way to say this. Any rectification on my sentence please?
