Hello!

Well, IMHO what newbie00 said - calculating acceptable band for analysed values, is used rather in situations when you have an exact 'middle' value, which is the standard and required one. BTW - this is used in quality management.

If the model is linear this is ok, but in other case the only way to decide if everything went ok, is to prepare the curve computed by an exact (expected) model, stimate acceptable difference and compare those two curves ;)

IMHO Excel is only a workaround to visualize data, but AFAIK Excel it _will_not_ cooperate so easy with anything else than Execl itself :-( Besides, if you are using execl, you have to decide yourself whether there are any abnormalities using a graph... Ha! So why do i need a perl program?! ;-> If you don't need a graph, why do you use Excel? Excel is also some solution; everything depends on what you _really_ need.

Best regards to everyone here. --tmiklas
