For those curious, it’s an American cemetery under US administration. It’s just located abroad.

I looked it up and France is 20 as the most common with generally up to 25. Spain is 20 average with 25-30 and max of 40. Italy, Germany and even the UK are in that range with UK being the longest now with 31-32 capping out at 40 generally. 50 is not normal for comparable countries. Are you suggesting that in your country 50 is normal?
