In case you're not joking the percentages aren't amounts of each chemical, they're the concentration percentage of those chemicals.

    ooh, it's a sequence of soaks, not a combined bath of multiple reagents in one container

    No like its a combination of fluids, but some only have a certain percentage of active ingredients. Like if you buy a liter of 97% isopropyl alcohol, it's 3% water. If you then combine that liter with a liter of vodka (40% ethanol) you have a 2 liters of fluid. In the resulting mixture the percentages still don't add up to 100. They'd actually half. Your finished product would be 48.5% isopropyl, 20% ethanol and the rest water (assuming its super pure vodka). Because the percentages didn't describe the amount of each in the final mixture, they described the concentration of 'active' ingredient in each individual solution. Idk if that's clear I think that's the best way I can explain it though.
