Yeah, I find this kind of hard to believe unless the V3 vehicles are somehow a lot lighter than what many have been speculating. Or maybe he means that 230tf is what they think they need to run them at to maximize reliability and is implying that they've been running them at higher thrust levels than that on flights 12-14 and just accepting the higher risk of engine out? Dunno, I feel like this may be another "my car is currently orbiting Mars" type of post from Musk.

Well, he's at least partly wrong about things:
>An engine fails on the ascent, two at the Boostback, after that it went from 11 to 5 engines on landing and the SuperHeavy strikes hard.
The booster had a soft touchdown, but they triggered the FTS to destroy the booster. This was both to validate the FTS, and to dispose of the booster after landing it. They liked what they saw enough to try catching the next one.
