Continuing the thought from yesterday, after some further thinking.
It makes no sense to divide correlations. It's weird conceptually and also the numbers you get are hard to interpret. Rather it seems most straightforward to use reliability-attenuated correlations and apply a SESOI:
Cor_att = cor*sqrt(rel_a*rel_b)
Apply (crud-corrected) SESOI (Cohen's estimates _might_ work) or whatever is defensible based on the plausible parameter space.
