"He really wasn’t that big, maybe 5’6 with an average frame"

So Ghoul should have the weight of an average 5'6 male

And according to these two websites (https://www.rush.edu/health-wellness/quick-guides/what-is-a-healthy-weight & https://www.medicalnewstoday.com/articles/323446.php) the average weight of a person of that height is 118 lb to 154 lb. Therefore this is our low-end and high-end

"After a brief stare down, he jumped. There was a good 50 feet between us, so I thought I would have a few seconds to ready myself but I was wrong. As if he was a video game character he soared from the tree and landed directly on top of me."

Considering the Protagnaist had ample time to ready himself and was still blitz it would be safe to say Ghoul crossed the gap in less time then an average person could react.

Average Human Reaction time is 0.3-0.129 seconds according to our wiki. I'll just go with 0.3 seconds for simplicity.

50 ft => 15.24 meters / 0.3 seconds = 50.8 m/s or Subsonic

Now we have the speed, time for the Kinetic Energy Output.

118 lb => 53.5239 kg

KE = 1/2 (53.5239 * (50.8 * 50.8)) = 69,062.9586 joules which is Wall Level.

154 lb => 69.8532 kg

KE = 1/2 (69.8532 * (50.8 * 50.8)) = 90,132.981 joules which is still Wall Level.

Conclustion
This scales both to James's Durability and Ghoul's AP.
