First of all, I’m really enjoying the tutorials. I have a question about the final 2.6 scale factor that was applied to the sphere.

If the target diameter is 21.59 to 21.83 cm, should the final scale applied to the sphere be somewhere between 2.159 and 2.183? It seems like the 2.6 is outside the target diameters.

Also, since the scale applied to the sphere seems to be working on the radius, not the diameter, I would think the final scale applied to the sphere would have to be between 2.159/2 and 2.183/2.

Sorry, if this seems trivial but I was just starting to get my head wrapped around the model to real-world scaling thing. During the challenge, I applied a 1.085 scale to the sphere which, I thought, would give me a final diameter of 2.17 blender units which then would real world scale to 21.7 cm.

Any clarification to my misunderstanding would be greatly appreciated.
