I just today received a new STI from Roy; the week of production is either 2507 or 2207 (don't have unit close by). They... said .... it was from a new shipment from manufacturer.
I know this date is apparently before the cutoff, but I did the dim test on the display, and it dims slowly, in increments, over a half minute + or so.
My dim time might be off....I didn't time the dimming, but it was definitely not all at once.
Would this indicate that it has been upgraded? Is this the best way of knowing?
