Thanks. Those are significant (percentage) differences.

Are the Point 1 spacers thinner?

FSA has 2 kinds of "wavy" spacers, which are lighter.

I have the "outside wavy" variant (part no. H2367), and here's the weight on my scale: 5mm-1.4g, 10mm-2.7g.
(ID 29.0mm, wall thickness 1.3mm, the ridges are 3.3mm thick)

You can see both types here: http://www.bicyclestore.com.au/parts/headsets/spacers-top-caps.html
