Did I Overfill The Transmission?

Ok dumb question, it most definitely is overfilled, but I'm not sure how I went wrong.

I did the ATF in my '13 Sport. Fully drained the pan, replaced the gasket and filter, put it all back together, and filled 5 qts of ATF +4. I have the NAG1 5 speed and it calls for 5.3 qts for a pan drop, so I figured putting in 5 would be a good start and then I could top it off if needed. I cycled it through the gears, drove it around the neighborhood, and this is what the dipstick shows whether it's cold or hot.

I suppose I'll just have to loosen the pan a bit and drain out a quart or two and then top it off to the right level? If anybody has some advice or knowledge to pass on I'd appreciate it!

So the manual says leave it in park, but upon further inspection of the dipstick it says check it in neutral.

Even in neutral it definitely was overfilled, so I drained out about half of the pan and added back half a quart at a time, checking the dipstick at operating temp each time. It seemed that I got it to a good level, so I drove it around for a bit and then checked it again and now the level is slightly above the hot label. The fluid was thicker around the hot label and the stuff above it was thinner. There was even some fluid well up the dipstick. I feel like the level is good, but due to driving the level might be fluctuating somewhat.
