Some pans have the capacity for an extra quart, some don't. You'll wind up with the crank slapping the oil before seal leakage. The seals only start blowing out when the oil level is above them consistently.
Oil level is 1 inch above the Full dot

I'll let you know when that starts happening on my Vette, but you'll be waiting a while, because after 7 years and almost 100k of overfilling the engine by one quart, it's not caused any problems.
Yep, it's unlikely to cause much.
In the old daze at the road course we routinely overfilled our cars a bit to compensate for oil sloshing around in corners.

4-5qt ha.. 2001 hyundai accent with 3qt pan..
oil change with filter was under 3.5qts.. thats absurd..
to the OP 1/2" is ok. dont OCD about it..(IMO)
next time add the capacity in the manual -.5qt
then drive it for abit.. off ramps etc.. fill up the oil filter .. then check it after 2-3min and finish topping off

I always put in what the manual says. I only use the dipstick to check the oil level in the morning. I put 4.5 quarts in my 1999 Buick Century and 3.9 quarts in my mom's 2010 Honda Civic.
