Hi Darth. They might be impressive excel skills but I cannot take the credit for them as the excel sheets are what I have found online. My excel skills are a bare minimum and with ill health I don't have the patience to learn further. The sheets are not really what I initially wanted and have yet to find one that has everything on that I think would give more of an insight to results. If you could help set up a new sheet that would be great but that depends on the cost lol as being a pensioner in ill health money is at a bare minimum. Anyway let me know and I can send you my thoughts (if you can help, send me a contact e mail address). Cheers and good luck today
