While watching different I've noticed that load times between the PC version and Switch of the game seem to be a bit of and after going through and timing the loads it turns out that in a standard Demo% run on PC version saves around 52 seconds on average assuming the load time are the same between demo and standard version in an Oltura% run it PC versions saves up to 8-10 minutes alone on loads.
A solution to this would be to time runs through In-Game% which would mean no one loses any time due to loading screens however it could be very difficult to time loading screens and verify across a several hour long speedrun and I don't think there is a perfect solution to the issue.

For single player you can change what events are active on the map such as winter wonderland or the anniversary event. What happens is that, specifically in Eggcelent adventures, you get the dino candies from oviraptors that increase your creature speed by 5,10 or 15% even to flyers, depending on the rarity which over an hour long run could be extremely. Question is, are events allowed or not?
