Could the US Standard-type battleships have received much larger speed increases during their refits?
Short answerProbably, if the Navy had enough time and made the speed increase a genuine modernization priority.
NotesThe Standard-type battleships probably could have received speed increases comparable to Japanese reconstructions. That judgment depends on the Navy having enough time and genuinely wanting to pursue the work. No automatic improvement or detailed engineering figure is claimed. Modernization priority and schedule appear to be the limiting conditions rather than an absolute technical barrier.
