Presumably there's also a cost for the lucky/unlucky titles for each option. (as well as for the chest title, and gold ID).
Perhaps that's all boardwalk'd, but I find I 'd prefer opening NM chests to get lucky up... However, I end up opening mostly HM chests, as the loot drops are better there (and I don't just run 1.x minutes per chest without doing anything else - how mundane). Thus my high unlucky and low lucky title...
As to your valuations for golds/grapes, they make assumptions based on the fact that you'll be camping in kamadan, hope-spamming to sell (and hoarding items/mods/inscriptions). These days I pretty much just vendor 15%/x inscriptions on the golds they're on - the wasted time and inventory hassle isn't worth the supposed 500g/1k value that you *may eventually* get... If it's worth less than ~5k, it ain't worth trying to sell (IMHO). Now, on the other hand, if it's 250-stackable...
(unid gold ~700g, not 800g (you used 800, not 750) - and it takes a lot of time to sell them even at that price. Your purple values are more in line with vendor trash tho. I'm not sure I believe NM golds drop 25% - seems more like 13-16% to me, but I've not collected stats on 1000 NM chests =D. And HM gold drops seem more like 80-85% to me - again no stats, just feel...).
