how to record and calculate a 6 stage program with a spreasheet

1) I didn't put 33 days , the row number doesn't equal the day number because the first row is for the column's title. I didn't find a way to remove this "problem".

You could take column A as day counter and move the existing content one column to the right.

I've done what you said, now everything is more clear, it was bothering so now it's gone :@.
I'll upgrade to the new version when I'm sure everything is correct. and maybe upload a video if possible.
