What, no Reg Park?
205 pounds at the height of 6'1" is BMI 27.1. At 6% body fat, that's FFMI 25.4.The following year , pictures of Reg Park and rumors of his genuine 18 inch arms started appearing all over the Physical Culture press, along with the news that he had bulked himself up to as much as 230 pounds. He then dieted down to a weight at which he felt he achieved maximum muscularity. Park now weighed in at 205 pounds, with a neck of 18 inches, chest 49½, waist 31, thigh 25, and a 16¾ inch calf.
18" arms and 49.5" chest are in line with the measurements of other high-profile bodybuilders at the time. Steve Reeves had 17.5" arms and 48" chest.
The Governator, same height as these two, was reported to have 22" arms and 57" chest at the peak of his career.
Here's a different paper that gives slightly different numbers but it too says that, for 40-59 yo males, 85th percentile is 20.9 and 95th percentile is 22.4.
It also depends on how recently you've been in the gym lifting weights. Personally, I'm in the same boat. I was in the gym doing weights twice a week from October to December, then did a hydrostatic body fat test and it came up with FFMI 21.5. I don't think I was higher than 21 in the summer. For my & your height, the difference between 21 and 21.5 is 3 lbs of muscle.
(Also, there's no contradiction between the low 85th/95th percentiles and the ease of gaining the first few pounds of muscle. In any given month, fewer than 5% of adult Americans regularly work out in a gym, and even fewer hit the weights.)

I'm right around 14.5% currently give or take depending on the day.
I view weight a little differently than I used to when my goal was to simply lose it, I weighed around 200lbs at one time and now I'm training to race currently. So for one I stopped looking at weight in lbs and switched to tracking in kilo's.
I'm 5' 6.5" and ~67kg (~148lbs) with a FTP hovering around 3.8 watts per kilo, just by losing a few kilo's I could push my power to weight ratio up to 4+ watts per kilo without having to work quite as hard as it would take me to gain the extra 12 watts. However in the time I'm losing that weight I'm also increasing my power through training so that power to weight ratio goes up even higher. I'm aiming to get to around 10% body fat without trying to gain too much muscle through eating healthier and then see how much that affects my performance as sometimes losing too much weight too soon can sacrifice performance.
Willoughby ideal athletic weight/waist assumes well developed muscles all around (FFMI ~23..24?) and low body fat. For you, it's 30". A pre-steroid era world class bodybuilder with your height might get to 31-32" (as mentioned above, Reg Park was 31" at 6'1" height, but that seems to be below average.) For an average male who does not do crunches, this article gives average waist ~29" at 15% BF, 32" at 20% BF, and 36" at 25% BF.
