Interesting. Here's the pair, and looking at it on a 5m chart, it's instructive to watch the prices move through the clusters.

This is the most likely explanation why the raw index does not match the tracking index ETF. From this I conclude that since we can only trade the tracking ETF, that the raw index clusters are less important and could be removed from the presentation with no impact on performance.
