There's a pretty simple question, the answer to which I haven't been able to figure out...
If you are trying to aim a weapon that has a 10 strength requirement, will the detrimental effect of not meeting that requirement be the same whether your strength is 1 or 7? In other words, does your accuracy suffer as much with a strength of one as it does with a strength of seven; or does it work such that with a strength of one, your accuracy is terrible, but with a strength of five, it's only sort of bad, and with a strength of 9, the accuracy penalty is barely noticeable?

Conversely, does having a strength ABOVE the weapon's requirement improve your accuracy with it? I noticed that, with a strength of 7, I had a MUCH higher chance in VATS to hit with "Lucky" (which has a requirement of 3) than with a 12.7mm Pistol (which has a requirement of 7). Perhaps it's just that the 12.7 is inherently less accuracy than "Lucky".

All good questions i've been asking myself, but sadly haven't found any proper documentation on.

I've tried to test this myself ingame, using the console to increase/lower strength.

With the AmR rifle and weapons handling perk, you need 6 strength.
When i lowered this to 1 i felt a noticably change in the reticule's steadyness. But increasing my strength with 1 point at a time didn't really seem to have a big effect, atleast not in real time targeting. Having more than the required strength didn't seem to do much either, so if all strength values have different effects on the steadyness, it's to a very small degree.

What i didn't think about testing however, is the accuracy ratings in VATS. Come to think of it, that might be a logical place to look for any changes.

I seem to be able to aim Anabelle (unique Missile Launcher) better with 7 STR than I am with 6 STR, the requirement is 8 STR. :shrug:
