Hi nobody, Ohlbe and everybody,

» » In his response Helmut mentions SD calculated from 2 or 3 replicates. Sorry Helmut, but I would consider any such value as meaningless.
»
» Exactly. Trash in trash out. SD is not erwartungstreu. Start with n=20+...

I stand corrected – you are both right. Is a stupid idea.
