Re: "Only 20 bar low?"
if they didnt care about the safety, theyd have attempted to launch, which probably would have been an aborted launch, or one with not enough raptors operating and might have led to another rud.
a scrubbed launch in the context of an experimental prototype test campaign is perfectly normal situation, heck its perfectly normal in a rocket thats considered proven and reliable. and shows they wanted longer to check the data to troubleshoot the problem, though they likely already knew where the issue was but couldnt fix it during the countdown schedule.
as they can only hold at the t-40sec mark, which is a planned hold point if its required, its not some random OMG we must stop the launch now panic just before launch (hold hold hold is the official call for a hold condition as its clearly heard & understood on the flight controllers loop, again not someone just panicking and shouting), for between 5-10mins it seems before temperatures of the propellant load exceed their operating criteria.
it was all perfectly normal and dealt with safely and properly, no ones trying to schedule things for the sake of it. but you absolutely learn way more the more you attempt to launch rockets like this, than sitting on your backside for 2 years.
