Smaller number equates to a tighter choke, which typically creates a tighter shot string for better patterns at extended distances
This is 100% accurate as a general statement. But keep in mind, if you go too tight the pattern will become "overchoked" and you will start getting erratic results. If you look you can find some super tight chokes out there, but tighter does not always equal better. Lead can typically be choked tighter than HTL, bigger pellets (i.e., 4 shot) often prefers something a bit more open that smaller shot (i.e. 6 shot). There are too many variables to account for which is why there are so many different options. You can get advice on a good starting point, but if you are trying to optimize your pattern, plan to try a few different combinations.
