Thanks! Please see my comments.
sum(len(x for s in strings) is consistentely faster than len(''.join(strings)), see https://claude.ai/public/artifacts/6a4c33e7-9ad5-4078-8ee7-e343984ce087

Better check the theory and the len of the string to know if we're going to truncate rather than checking the full length of the result after the fact.
