Sending out-of-date unofficial scores to potential advisors, weird or no?

[mockturtle]

I'm looking into Biology Master's programs and did well on the GRE in 2015, but that's unfortunately too long ago to actually submit those scores anymore. Some of the PIs I'm considering reaching out to ask to see unofficial scores if you have them, and I can't decide if it would be weird to include expired scores in an email, or weird not to include them when I have them. It might not be until November that I actually retake the exam, so I'm either sending them these score reports or nothing. Thanks!
