Hi David,

Thanks for your prompt answer. I have put my understanding in a simple spreadsheet. I have found that there are small discrepancies in the calculated values between values of Table C-3 and C-1. I may not be correct.

I have just wanted to introduce the speradsheet as an attachment, but I could not find the option for it. If you can send me an e-mail I will forward the spreadsheet.

Thanks and kind regards,
