Hey guys I saw this new video yesterday where a crew of athletes/enthusiasts were doing some sick features and what caught my attention the most was one guy attempting the CTI and was actually pretty close to Benincasa's (the one from the 2nd photo).
You can watch his CTI work and attempts starting from 7:06 with the best attempt at the end just before the credits, but you might as well just watch the whole video anyways since it is pretty sick.
I think you just need a very strong MU transition that is a lot straighter than normal + plus exceptionally strong pulling strength for the CTI based on my observations from the video.
