I recently published a web "minigame" (it's just a prototype) that is perfect for testing the mouse and measuring our expertise and reflexes. And it can be useful to warm up before a game.

The graphics are absolutely hardcore, to the taste of the top players

How to play:
There are 3 play modes: normal, evasion and tracking.
The challenge is shoot to 10 static targets (normal and evasion).
NORMAL MODE:
Each objective remains on screen between 0.8 and 1 second. (some players kill me in 0.0

The score for each hit varies depending on the distance in pixels to the center of the target and the shooting time in milliseconds.
This is the formula: score = 400 - distance x 2 - time / 10
EVASION MODE:
Each target remains on screen until it is shot down.
The targets are mobile and reacts to our actions.
The score is the same than in normal mode.
Bonus:
- Distance to target center < 5px : +400 points
- Shot time < 400ms : +1000 points (I got this bonus only 1 time)
- Failed shot : -400 points
It's meant to be a form of training to use the lg.
In this test we must hit with the pointer as long as possible (the test ends in 1 minute) on the target.
Score system:
- Every second we shoot on the target: +10 points
- Every second we fail: -10 points
- Every second we do not shoot: -0.5 points

Here is the link to play: https://jjcapellan.github.io/aimingtest/
The code is open source : https://github.com/jjcapellan/aimingtest
Notes:
I recommend using Google Chrome to play it (I confess, I've only tested it with this

In a next version I will add a tracking test (lg style).
And here is my best result

Any suggestion is welcome. I hope you like it.
I'm curious to know what scores others do ...
Regards.
