I can't up-vote this as it stands because the code isn't runnable, or easily mind-parsable. Provide complete sample data and a script that demonstrates that it works, and I'll look again. — Paul White4 hours ago
@PaulWhite You are too polite. The format in their code is just horrible I think.
Something about catching flies with honey vs vinegar perhaps.
I did try adapting the code to work with the question's sample data, but it identified every row as qualifying, which would be wrong. I didn't say anything or down-vote because I might have mistyped, or misunderstood how it was intended to be used.
Or the code could just be complete crap, who knows.
@Lamak Any kid (like yours truly) who played lightsabers with sticks as a kid got to realize the need for a lightsaber cross guard to avoid "ha ha I just sliced off your hand". My question would be why don't all other lightsabers have crossguards. My guess when I was a kid is that when lightsabers clash, they're sticky and can't slide over eachother.
