I have added an arc that seems to make for some interesting relationships
At .2222 you can see the distance between U2T2 is the value of one of my constants
while 1/2.53 which is the other value of the constant in my equation also gives
an interesting relationship between the value of Sigma the tangent Line to the Point " U " of the Arc and the Green Reference Line that is used to calculate the Normal Probabilities.
