When I was a kid, the oft-quoted figure was 10-20 billion years. By the time I was a young adult, it had been narrowed to 10-15 billion years. When they came out with the study showing 13.7 billion years, I was impressed that they had the confidence to quote it down to a 100 million-year window. It would be pretty embarrassing if it were found to be substantially off that.
Yeah, Lambda-CDM gives us the current measurements but I'm sure I saw a probably-reputable article recently that suggested that some celestial object measured 15.5 billion and therefore shouldn't exist. It didn't go on to say whether there was an error to be corrected in the specific measurement or changes to the model needed but I understand that 'exceptions' are being discovered fairly frequently.
