at the moment, for my work it's fine, but if you go ahead with the work...good luck1
Cool no worries, Ive played around with it a bit and Ive gotten to the point of not caring, just one other thing are you sure about the K-1 as opposed to 1-K? following your original problem and your solution I think you may have the K on the wrong side of the equation (line after 'introduce new variable (x-mu)/(sqrt(2)*sigma)

I hope you dont take offence, Ive just played with the algebra a few times and always end up with 1 - K.

Keep posts like this coming!
