The n-odd-prime-sum-limit (abbreviated n-OPSL) is the collection of all just ratios with a no-twos Wilson height that does not exceed the integer n.
This concept was noted by Tristan Bay as a way to measure how accurately an EDO approximates just intonation with lower primes weighted more heavily. Specifically, the idea is to use OPSLs as an alternative metric for consistency limit either instead of or alongside odd limits.
