3) Depends on the scale. If the task was running for 60 minutes then you would only have to wait 1.87 minutes which is a massive difference.

You are also forgetting the psychological impact that a few seconds can make. After 3 seconds of waiting without any progress indicator you've generally lost the attention of the user and they will do something else in the meantime.

When your talking about spinning up a MASSIVE number compute threads/servers >128 instances. This also takes a non-trivial time.

You really aren't seeing the forest though the trees. What I'm saying is it is a trade off.

Time gain: 1/2^x

Resource spending: 2^x

Figure out where the intercept based on cost.
