Well, I have spoken a few times with David since I first initiated a position in 2017.

He mentioned in the last stocks down under conference (video is on Youtube) that retention of 1 day is excellent, and orders of magnitude better than DRAM - so we know thats all we need to be attractive for a buyer - not months or years, even 1 day is 'out of the park'.

We know he has said recently / multiple times that they have proven retention in platform lot 4 when the 'power is off'. What does that mean?

I take it to mean more than a few minutes - most likely a few hours to a day. We know the results are significantly above expectations - so likely up towrds a day.
