That's just moving the goalposts. Not really adding anything to the argument here. The argument is just graduate students, not subset of graduate students that is impossible to measure with any accuracy based on available data due to your completely arbitrary and nebulous definitions. Also, even if we take your new arbitrary and meaningless 'definition', we can no longer use the key word from the original discussion: ----most----. My point stands. Non-native graduate students skew older than native students by quite a bit.
