Twist rate for the 380 ACP is essentially 1 turn in 10". That means inside the human body it basically turns a single revolution assuming it passes completely through and is not impeded in any way. Therefore, the "cutting" action is nil hence compression-type terms such as "crush cavity" and "stretch cavity" are used. One of the false accusation made against the Winchester Black Talon was they "cut through the human body like a buzz saw". It wasn't true then and it's not true now.
If I'm ever attacked by a Jello monster, I know exactly how bullets will always perform. Gelatin is a comparison media used to provide a consistent test bed for performance comparisons from bullet to bullet. It may well be the best and most humane media available, but to place all your faith in how a bullet performs in gelatin is questionable at best; fatal at worst.

My understanding of the gelatin testing is that 10% ballistic gelatin closely simulates the same type of resistance that human muscle does which gives us a pretty good idea of just how deep we can expect a bullet to penetrate the human body, but on the other side, gelatin does not simulate the stretch and permanent cavity effect very well.

Gelatin is generally OK for its representation of the permanent cavity, but what drives me nuts is when folks mistake the stress fractures and fissures seen in gelatin for what will occur in tissue.
Based on the Underwood/XTP gelatin test done by Shooting The Bull the underwood did not perform as well as other brands using the XTP bullet did.
I' convinced that increasing the velocity of an XTP bullet is a negative and that this particular bullet has it's best performance in less than 900fps range.
When the XTP in 380 gets up to 1000fps it expands too much which reduces penetration.

The poster I was referring to was talking about an Underwood loading of the Lehigh solids that are the subject of the OP. I would expect them to over-penetrate with higher velocity since they don't expand like the XTPs.
I guess the proof will eventually be in the pudding. Actually, after seeing the saboted slug in the one video I'd like to see the results after some eventually use these on deer and hogs. Post-mortems compared with other normal saboted pistol rounds used in those situations. A hog's shoulder shield and thick ribs should tell the tale.
It may sound ghoulish, but an experienced hog hunter will be able to tally the effectiveness with time.
