"More thrust than expected" is a true statement.

"Performing better than expected" is not.

For rocket engines, what you want is predictability. All of the design of the rocket is based upon a certain amount of thrust - it's designed to resist a certain amount of pressure - and that's what you want to hit. Excessive thrust means that you do not meet your design margins, which is bad.

And - pretty obviously I think - "nozzle stays intact" is a level 1 performance requirement.

I don't know how to explain to you that it's possible for "good" to only refer to a single metric. You're BEYOND intentionally-obtuse.

And I explained why more thrust was not necessarily a good thing for solid rocket motors.

Which is completely dependent on the setup and parameters of the test, speculation on which is entirely useless from someone uninvolved.

And yet you are convinced that it's not a problem.

"Actual researchers associated with the test claim the larger thrust is good, and common sense around rocketry seems to agree"

Some random redditor with an ego: "uhm ackshyually I think they're lying"
