Check if we can measure effect of Doherty threshold in the real world.

Using a calculator (programed by yourself or not),

- Run a small user test with at least 5 users as in:

- ask users to perform some numerical calculation task on the calculator. It is better if it is the task is exactly the same for all users.

- After user completes task, change the delay in showing the result of the calculation.

- Measure the feedback of user with a scale from 0 to 10 or similar while changing the delay.

Can you see if the Doherty threshold impacts the satisfaction of the user?
