Hi,

re TY, for myself like to go with one more decimal point originally..

and then make the decision to go to less accuracy to match parameters

used on the set Up.

ME =  = .71

  6.4 - ME <  < 6.4 + ME

  6.4 - .71 <  < 6.4 + .71

5.69 <  < 7.11

 5.7 <  < 7.1

Note:

80%	z = 1.28155

90%	z =1.645

92%	z = 1.751

95%	z = 1.96

98%	z = 2.326

99%	z = 2.576
