[RealTracks]

We now specify the exact facility and tooling the raw materials are manufactured on. Our first shipment of raw material was slightly different than what we originally tested. I think some units may have shipped that came from the wrong facility, but I can't confirm either way. It was a very subtle difference but noticeable. I checked and it looks like your Track Pack 20 was the 6th set shipped after the release date. The dNaNo's were not out then so I don't have any data on their performance. The epoch performance was only marginally different. However it may be exacerbated by the dnano's increased performance. Your new Track Pack will tell all.
