R18: example 14 Efficient portfolio weights exhibits

[silvermonaco]

Hello,
I have been struggling with the exhibits provided in the material showing the surplus efficient frontier deviations and weights.
particularly exhibit 34 on page 245 (example 14)
with the x axis representing standard deviations and the y axis representing weights, how does one interpret or plot the 60/40 equity bond mix? Not sure how to read it.
Appreciate any guidance with this.
thank you

your y-axis could be surplus/asset ratio or surplus= % net asset also. It is then 100% 0f 60%
