It really depends on the charge/discharge conditions that the particular test is using.

True.

You can do testing in the lab that is way harsher than typical usage or you can make it easier. In terms of this cycle testing for Li-ion I would say that typically the lab testing would be harsher than real world primarily because lab testing is done between 0% and 100% depth of discharge constantly where most people are charging their batteries much before then and only cycling them at high rates periodically.

You are right, but we should see what they want to demostrate in the lab test: that the tech works or to have a way to make a sensational announcement based on some data ?
If you put that battery on the market, the 6000 cycles still stand or they are only a lab result ?
Aside the harsh or easy charge/discharge cycles, what other condition they tested ? A battery on a bench has different problems than a battery on a car on the road.

That said, if the tech works really has announced, it would be great.
