In the section 'Fixed at both ends. Load at any point', the deflection at the load is given as y = Wa^3b^2/6EIL^3. However, where load is in the centre, i.e. subsituting a = L/2 and b = L/2, the load deflection in the equation becomes:

W = W(0.5L)^3(L - 0.5L)^2/6EIL^3

= WL^3L^2/192EIL^3

= WL^5/192EIL^3

= WL^2/192EI

which is not correct, because it should be WL^3/192EI
