I don't know if the second and third one count because those are glitchy. But I think the first one is fine.
(btw, in the third you have to go frame by frame to see the max velocity)

I'm afraid this can't be accepted as pecs and glutes are not applicable for several records (highest speed and highest body part for two off the top of my head) due to how incredibly buggy they can be. Glutes specifically can easily rack up hundreds on the speed counter for seemingly no reason when they move erratically (see attached replay for example).

Due to the unreliable nature of replicating these "glitches", we've disallowed the use of the aforementioned joints in record attempts such as this.

Additionally, the highest speed record specifically doesn't allow for dismemberments. Have to keep your ragdoll whole for this one I'm afraid!
