I have every confidence they will work this out. I would hate it if people benchmarked my code whilst it was still in development and extrapolated the future performance from that.
Chamber pressure, mixture ratio, and throttle limits can be adjusted operationally within the hardware’s margins. Engines on reusable vehicles are regularly swapped, inspected, and replaced. Process changes, minor part upgrades, and material improvements get introduced into the production line.
Flight data drives continuous tweaks to control software (throttle profiles, mixture ratio schedules, startup sequences, health monitoring). Those are software updates
I want you to look at the evolution of the capacity of Falcon 9 over its various design iterations. There certainly was a lot of optimization leading to substantial growth in capacity.
Well said. I'd also add not everything is unachievable just because it hasn't been done yet. A lot of people won't even update their priors once something is done (belief perseverance). I've lost count of the number of older people that tell me electric cars won't work whilst there is a perfectly functional one sat on my driveway.

But not everything is achievable just because we want to achieve it. Physics/chemistry also have a say in it.
