This. First the game rolls what you get, and then it rolls what you get from that bracket.

That's the answer Sanathlig came up with when he went through how the gacha works at release, based on the draws of two spacewhales. 1.5% is an assumption since when this data was compiled, non-Hime SSR weapons were in the gacha. But Eidolons and Hime had basically the same chance, so we're assuming that they're now 50-50.
