Very cool you’ve previously mentioned it—nice that we’ve both been thinking about it!
One proposal is a slight modification. Basically to use your example, you could (a) randomise the entire 250 or (b) you could rank the 500, give the ‘treatment’ to the top 150 say, then randomise 100 ‘treatments’ to 200 around (100 above and 100 below) the cutoff. I think both proposals, or a RDD, would be good—but would defer to advice from actual EA experts on RCTs.
