No just static compression.

Mine is a little more flexable...

I only created it as the link you posted in another topic kept taking me to a random page and not the file. guess it was mozilla that was causing that problem as its working now. Cheers for replying!

Hmmm....

I have no problem with it, I downloaded the xls file to my laptop and have all my figures entered and every time I check a variation on any of the figures, the result is just what I would expect.

It's a bit fiddly as to which cells you enter, but works fine.

Schrödinger's cat - so which one am I ???

Whos?

Thanks Keith. After trying your Excel sheet I found out there was a big mistake in my own calculation. I calculated a compression of 9,85 where it should have been 10,85. Oops...
