Took me some time to figure out that, e.g., -56/-76 for exp. 2 is due to sparkling cost. Also, -56 is for 4 Mutsukis, for 4 subs it's 40, for one sub and 3 scrap ships it's 10. If you want to include sparkling cost, having it referenced (together with resupply cost) may be helpful, I think; although, in some scenarios it can be disregarded (e.g., when getting enough ship drops scrap cost can be used as a cover for sparkling cost). For item rewards, linking Expedition/Introduction may be good (e.g., second item is for GS only, with 100% chance), see here: bucket rate is different for NS and GS for exp. 11. From the same link, you can measure "sparkling usefulness" for each expedition (using differences between scores).
