Good catch. The algorithm is right (the earliest even entry has index 0), and the description was wrong.

To address the issue, I changed the description of the |pattern| simply to "A vibration pattern represented by a list of time entries." and added your example to the non-normative Examples section where it fits better. The algorithm is the normative part.

The Editor's Draft [ED] has been updated. A new release [TR] with this fix will be tagged later as per the W3C process. Meanwhile, I encourage you to refer to the ED for the latest.

Let us know if this addresses your concern, and thanks for reporting the bug!
