Well that's the thing- they have the slightly-higher CR DP costs but they ALSO have low CR/day recovery speeds. So the supply/day recovery cost runs twice as long & expense-wise puts them a tier-higher.
that's not how it works. ^^ the shown supply recovery cost is
per deployment, not per day spent recovering the lost CR. the time it takes to do so is already taken into account.
for example, a Wolf with 20% CR cost per deployment, 10% CR recovery per day, and
5 supply recovery cost per deployment will take
2 days to recover the CR lost from being deployed once, consuming
2.5 supplies per day.
sidenote: this does mean that two ships with identical supplies per deployment cost but differing CR per deployment costs will require differing total supplies to recover the same amount of CR, which matters for how much it costs to fully repair salvaged ships, since those always start at 0% CR (or up to 40%, with the related industry skill). this is because the total max CR of the ship that ends up costing more equals a larger number of battle deployments.
fortunately, the ship salvage panel (where you pick which ships you want to recover, and which you leave to be scrapped) already shows the total supply cost for fully repairing each individual ship, so you don't have to do any calculating for this yourself either.
Huh, that might just be a discord I actually use, thanks for pointing it out!
you're welcome! :]
