In response to Volker comment I agree with, the next to the last string in my write up is the evaluation of the uncertainty of A. As I already showed, my and FFX expressions for A uncertainty are identical.</div>

Please find below the analytical evaluations for BSA uncertainties: a) the absolute uncertainty values \DeltaA (next to bottom string); b) relative \DeltaA/A values (bottom string)</div>

As you may see, the relative DeltaA/A uncertainty is described by the product of two terms. The second (from left to right) term is proportional 1/sqrt(N+-N-), as FX mentioned. However, the first term 1/(N+-N-) inflates DeltaA/A values for A<0.1, which a typical
values for the BSA in the N* region. For this reason, statistics matters, in particular in the resonance region where the statistics is much smaller in comparison with the DIS region.</div>
