In the long run, the range of counts near 0 will be canceled because it is as likely to go +0 than -0 assuming you are flooring correctly. Therefore, the only variable left to be considered when comparing tc=0 to BS advantage would be playing deviations, right ?
By the way I like the way you define and explain things as they are easily understandable, even for me ( I have a poor English )
Thank you Norm
