You are on the right track.
I checked the recipes under Carpentry including the whittling. There is no code calls to the "skill advancement" modifier so they should all progress "normally".
So from this it sounds like if a mod recipe uses Carpentry skill, I can assume it will train Carpentry more or less proportional to the amount of time I spend on it, and this isn't something modders have to specify as it's the default. Thank you, I will keep at it.
Unless a modder adds the code to the recipe to change the skill gain rate it is at the default.
The ones I checked didnt seem to have that modifier listed.

I like the idea. I dont have experience with making it and am pretty open to letting someone else organize that.
The actual recipes may change over time.
It might be helpful perhaps for some of the more complex items like the boats or furniture to explain the production chain.
A list of how to get an iron piece starting with ore would surely help new players. Same with clay.
