Bummer that E6 disappeared, was really hoping to see that tick back upward with idle time working.

Not sure if you ever mentioned this, but what was the write speed in Anvil's app with LTT active? If it's anything like the 16-18MB/sec from AS-SSD, then LTT write speeds were almost surely faster than the lifetime slope. 16MiB/s = ~21 disk writes (with parity space, so 64GiB) per day, or 7700 P/E cycles a year, which is way more than what IMFT 25nm is rated for.
