Strange notation
I took the liberty of changing this
 * $$\Delta y_1^s = y_1(p_1', m') - y_1(p_1,m)= \text{Ys -Y1}.$$

to this:
 * $$\Delta y_1^s = y_1(p_1', m') - y_1(p_1,m)= Y_s -Y_1.$$

If for some reason the "text" style is needed for Ys and Y1, could one not write this
 * $$\Delta y_1^s = y_1(p_1', m') - y_1(p_1,m)= \text{Ys} -\text{Y1}.$$

with a proper minus sign instead of that stupid-looking hyphen? Contrast the two:

\begin{align} \text{hyphen:} & \qquad \Delta y_1^s = y_1(p_1', m') - y_1(p_1,m)= \text{Ys-Y1}. \\ \text{minus sign:} & \qquad \Delta y_1^s = y_1(p_1', m') - y_1(p_1,m)= \text{Ys} - \text{Y1}. \end{align} $$ Michael Hardy (talk) 17:40, 12 February 2019 (UTC)
