I just realized that I forgot to account for alpha (as I often do, for some reason) when calculating WSC. Also forgot that Red Curry gives +1 AGI. This changes pre ring WD to 133 with Stormsoul adding either 3 or 4 (2.26% & 3.01% marginal gains, respectively.) The pre ring AGI values that will yield +4 to WD are too sporadic to list with a simple pattern. Either way, I guess that means Blade: Hi will likely always favor Epona's, although in some cases, not by much.
