Calculating lead hardness for blending

I thought I would share this easy way of blending lead of different hardness to create a new hardness.
Effectively it is blending known weights of lead at different hardness. I use the Lee lead hardness tester to give me a rough idea of the scrap lead, so if you need any testing let me have a piece when you see me at the range.

A worked example is shown below:

The youtube video below shows how easy it is to measure the hardness, also where I got the idea of the calculation.
