It should only be attempted with a minimum 10x garrison strength preferably 20x to reduce losses (but less if the walls are breached). So in answer to your question it is only worth doing when you can sustain a 40k infantry only stack without reducing the strength of your main armies. However, now that you can't 100% a nation who has allies in a war before 5 years are up it's pretty much never worth it.

It's still worth it when you get to the province already partly sieged. Say if you find it with a 500 garrison you can safely assault it with a 10K+ army instead of waiting for the ticking to grow from -60 (specially if there's attrition)

Assault level 1 and 2 forts if you have at least 12-15x their garrison in infantry.

Assault level 3-5 forts if you have 20x their numbers in infantry, 10x for broken walls.

Do not assault level 6-7 forts.

Late game when dominance is assured, a 100k infantry stack can speed up wars a lot.

Best time to do it is when there is a big stack of French troops supporting your siege.

Second best time to do it is when a territory just gets taken and has a low garrison.

Third best time to do it is when the walls are down, but the siege would last a while longer.

Coastal, non-cvlocakde province with breached walls, that's the only reason to assualt besides retaking a province.

Wow, not sure why I never thought of this... that'd be an awesome way to make France needlessly drain their manpower.

I usually only assault when for whatever reason I need to end the war right away, and I need more warscore or I want to conquer the province that I'm assaulting.

When I need to peace out quickly and want a specific province. As in, I've struggled for years, have say 30% WS, walls breached but a doomstack is coming around... So I assault, win the siege before the ennemy comes in and beats me and peace with say 2 conquered provinces rather than one. Otherwise, it's hardly ever worth the waste of MP. Except for wargoal perhaps, to get more quickly ticking WS, or capitals (to get rid of -5 "X controls its capital" modifier).

I only assault recently sieged provinces while the garrison is still basically empty.

It is NEVER worth it unless you're either:

1. In a desperate situation. I ordered an assault on an Ottoman holding because I thought they'd accept peace if I took the wargoal and knew that if their army showed up I had no chance. (I lost 20K men for nothing.)
2. Massively, massively superior to your opponent in general and don't mind dropping 20-40K manpower for nothing.

Oh, and of course if the garrison is tiny, <500 men.

1.) The garrison is tiny (retaking a province that your enemy just sieged).
2.) 12:1 or better with no breach.
3.) 4:1 or better with a breach.
4.) Throw away a stack of outdated mercenary units for kicks.
