You are right; I should have been more careful. Still, the medicinal effects of CQ and HCQ are very similar (as are the molecules, a single hydroxy group makes the difference. Even the CDC page I linked lumps them together) and I at some point I began to assume equivalency in all respects. I looked into this a bit more and it appears HCQ is favored in modern times because the hydroxy group reduces the toxicity. Thanks for pointing that out.
Having said that, the dosing in the UK RECOVERY trial (2.0 g in first 12 h, 0.4 g every 12 h for up to 9 days after that) still appears high to me. For acute malaria treatment, 1.6 g in first 24 h/2.0 g total in 48 h is standard; for prevention, the standard is merely 0.4 g per WEEK. Human toxicity studies are lacking (at least from what I could find) but if HCQ is really 2-3 times less toxic than CQ that puts a toxic dose of HCQ at around 3.0 g/24 h, thus the RECOVERY trial dosing is still cause for concern, especially given the long half-life of HCQ, many weeks. But it no longer seems maliciously bad. Good job.
Not giving up on it though. Lots of publications now supporting my claim about the benefits of early administration. The first one linked therein, Ladapo et al., is a meta-analysis of five RCT studies. 24% reduction in cases found, p < 0.05, tells me HCQ works. And those studies were without regard to zinc, but I guess that's just magic to you.
