That's fair enough. Just basing my opinion from past PR word smithing. I remember a PR from 2010 stating "ready for mass production" and was told only couple months before units are built. Then many months later I was told it said "ready" not "started". LOL; word games people, all word games.
If "20 to 25 % more efficient energy consumption" means the same as "favourably to the high-end" to you, fine with me. IF it was as they previously stated I would have thought the PR would say "better" not favorable, but what do I know.
