At the end of each heist there is always a long unskippable cut scene followed up by the elite challenge requirements, Money, RP etc. But it is actually possible to skip these. The method could be controversial so i thought i'd just bring it up before anyone does it in a run.
After the flash at the end of the heists one of the players can disconnect from the internet or suspend their GTAV in task manager or even have a 5th player invite the entire team to a session.
Whatever way you choose you will save a huge amount of time. The 5th player invite is the fastest and only takes about 20-30s to load into their session. The disconnecting from internet or suspending your GTAV.exe in task manager are slightly slower 40-60s but still much faster than watching the cut scenes.
The cut scenes after each heist are as follows. (Pacific standard is excluded because the timer stops at the start of the final cut scene.)
Fleeca: 1m 40s Prison Break: 1m 10s Humane Labs: 1m 50s Series A: 3m 50s
This seems so manipulative that me and RNJesus have decided to disallow it for the following reasons
Requiring a 5th: This was the argument that was making me sway in leaning in favor of allowing this but getting a 5th would mean you would have to add that 5th to the leaderboard since he is by definition assisting in the run in getting a better time. Not to mention getting 4 players consistently for a heist is often a pain in the ass, getting a 5th just to have a chance at beating WR would be too annoying and would deter people away from running this category.
TaskManager/Stopping Resource/Pulling The internet. This constitutes too much to outside manipulation and is usually disallowed in other speedruns which is why me and RNJesus decided against it. Its so much akin to the GTA:SA audio device discussion surrounding disabling your audio device so you can skip cutscenes faster.
If there was a way of skipping the cutscene without the requirement of a 5th or outside manipulation then i would be tempted to allow it, but as it stands, well need to write in the rules that doing them methods would invalidate a run. Thanks for bringing it up, we'll keep an eye on runs from now on regarding it to make sure they are consistent with the rules. If you wish to dispute this please do so here.
