Sorry Guys I have given this formula every opp. and it has failed time and time again, the last straw was one I was two lines away from the hole, the dots moving either a 2 or a 3 no more.
Did the calculation and was was way off. I even went as far as to make a scale divided into equal increments and gave them the value . For inst. sq.= 30, 1/2 of sq =15, 1/2 of 15 = 7.5 you get the picture. Well all I can say is I gave it my best shot. It is stil a hit and miss thing.
Sorry Gold
