On the performance tab, the total/average session time thing is very inaccurate if your experience has multiple places players can teleport to.
For the experience session time, it shouldn’t take the average of the times between the places as that is inaccurate. It should add all the players sessions throughout the places up until they leave the entire experience.
The session time for Roblox benchmarks are correctly calculated in the way I described. The real time session time should have a toggle for average/total or switch to total entirely so developers can accurately monitor realtime bugs or decline in session time due to an update.
