So while I don't necessarily understand the reason behind putting several minutes of screenshots of the scene at the end of the scene, I didn't really have much of a reason to dislike the practice until I noticed a lot of the scenes are saying they are however many minutes long in the description and at the end of the trailer but are in fact several minutes shorter because of said screenshots.
Now a lot of the scenes at least say what the actual length is at the end of the trailer, but for whatever reason some just say the length of the scene and the screenshots combined; for instance the Moona Snake Poker Lady scene.
Personally I use this information to see how much "wet" content there is in relation to the length of the "dry" version but I believe it's an inconvenience for a lot of people for a lot of reasons.
TL;DR If you're going to put these screenshots at the end of the scenes (which I don't understand) you should be consistent in saying how long the scene actually is
