The stuff you find in Data\Editor\Templates\Stats are default versions of the stats files, but the ones that matter are what is in Data\Public\Shared\Stats. I don't know the specifics of the Scales mod, but if you modified SkillData.txt located in Data\Public\Shared\Stats\Generated\Data, the changes should be reflected in game.
So, if you just wanted to make some changes to skill specifics, you could create a copy of SkillData.txt from Data\Editor\Templates\Stats\Shared\Generated\Data and drop it in Data\Public\Shared\Stats\Generated\Data.
Lets say now you want to Modify Ricochet. Open up the copy of SkillData.txt you created and find Ricochet--make sure it is the correct version of Ricochet, because there are a few. The version used by players is listed as:
new entry "Projectile_Ricochet"
Under this line is the data for the skill. If you want to modify the base cooldown, in this case, it is:
data "Cooldown" "4"
You could change it to:
data "Cooldown" "7"
To raise the cooldown from a base of 4 to 7 turns.
