He probably just wants to eliminate RNG in his crafting rotations.. I know a crafter that's like that.. He did his lucis tokens with a static macro that gave 15-20% hq and just kept running it instead of trying to do a manual rotation because he doesn't feel comfortable with all the RNG. I'm not saying I'd agree with that decision, but it's what some people choose to do.
8FC3 lost isn't really such an amazing feat to brag about.. Especially regarding Manual II tokens which is hugely RNG dependent.. I got most of mine without losing a single FC3.. then ran into issues on my WVR book with bad RNG, I think I lost 10 on that one alone.
Anyway, I wouldn't use WN for 40 durability crafts but for 80 durability, WN2 does work wonders.
The basic SH2 -> WN2 -> Hasty x 4 -> SH2 -> Hasty x 5 -> rotation, along with a couple of hasty touches filled in earlier in the beginning with progress rotation can give you more touch actions than a manipulation/master's mend rotation.
Besides, your manual II token recipe only has 11 hasty touches and assumes going for Byregots on IQ 10 or IQ 11.. Of course you can adapt since you can take pretty much all the ToTT that comes your way, but really, looking at your results. It doesn't really seem to be any different than mine and it seems you got some very good RNG during the bait phase, you failed almost no bait attempts except during your CRP tokens.
