I see.
I chose the value without 50-100% for Craft weapons to be consistent with the main Ufopedia display.... Ufopedia says Damage=70 (instead of Power=70).
Whereas in UFO articles, Ufopedia refers to Power (not Damage), so I added the damage spread to calculate damage from power.
I don't mind changing it, but it will be inconsistent one way or another.
What's more important than the absolute numbers is the relative comparison of two weapons.
Regardless if the numbers say 50 and 100; or 70 and 140... the second weapon does twice as much damage as the first one.
There's also UFO DPS vs craft DPS. And there's total expected weapon damage vs UFO hitpoints.
In those contexts the omission makes the craft weapons look more powerful than they are. I discovered this because I'm working on a little craft/ufo balance mod right now. For me it's not a problem anymore, since thanks to your explanation I know what's going on, and I'm doing the same thing in a spreadsheet, but still, until I asked I was confused. I cannot be the only person who will ever think of using that screen as a quick way to check "can this craft weapon shoot down this UFO before it runs out of ammo".
A stats/calculations display is an opportunity to present real values to the player, precisely because Ufopedia is wrong/misleading (when it says "Damage", it doesn't actually mean damage, it means a stored value that happens to be labelled "Damage"). Being consistent with in-game Ufopaedia has less value than giving the player accurate info.
This could be fixed by showing the damage range in the Ufopaedia - which actually might not be a bad idea. But perhaps not worth the effort, the added visual complication, and departure from past practice. X-com veterans are used to pedia values being worthless anyway.
PS: btw. even with damage spread considered, the numbers can still be very far from reality... pilot skills, craft bonuses, ufo bonuses and alien race bonuses all affect the final numbers and can make the same weapon very effective in one situation and completely useless in another situation
Right, Extended features. Atm I'm working with vanilla mechanics, and use Extended solely because it lets me use a keyboard shortcut to Mind Control things.
Anyhoo. Thanks for the replies. Me, I'll be fine either way now that I understand, but for whatever it's worth, I think UFO and Craft values should be consistent.
