`<section>` elements aren't necessary here since they're not separate 'sections' of the document.
`<tbody>` elements are inferred and don't need to be mentioned. I guess you could leave them in for readability though.
Added a `<time>` element to the datestamp in the intro paragraph.

I'd suggest you:

- make the first cell in each row a `<th>` and then set its `scope` attribute to `row`.
- markup the units in the table with `<abbr>` elements, describing the unit with the element's `title` attribute.
- remove `target` attributes on links. Target has been deprecated.
