Properly tensioned chain is far better than "as tight as possible". This puts unreasonable loads on the components, and actually reduces its ultimate strength since the load is oscillatory and subject to fatigue.

The fraction of a watt consumed by a tensioner can be measured, but you'd never notice it.

Maybe doing it wrong works for you and your team, and that's cool for you, but that doesn't make it good engineering practice.
