Score components:
- Keystrokes
What it is: The general feel of the keypress, force, and travel required; tactile feedback. The graph is obtained from a single key, while the Peak Force, Actuation, and Reset Points are an average of eight different letter keys.
When it matters: The feel of a keyboard is a personal matter and should be considered carefully. A different feel will be desired for something like gaming or typing, but there's no universal rule.
Feel Graph
Key Switches
What it is: The technology used to activate a keypress.
When it matters: When you want a particular feel from your keyboard.
Feel
What it is: Keys have different feedback dependent on technology. Linear switches have a smooth operation and no tactile feedback. Tactile switches have a small bump around the actuation point, allowing the user to feel when a press has been registered. Clicky switches have the same bump as tactile switches with an additional "click" sound.
When it matters: A feel can be preferred depending on your use. Linear will be great for gaming, tactile will be good for typing, and clicky will be great for typing. That said, a gamer can prefer using clicky switches and a fast typist linear switches.
Operating Force
What it is: The maximum force the user needs to overcome to actuate the key. In the case of tactile switches it match the Tactile Point, for linear switches it is the force at the Actuation Point.
Value Feel
< 45 g Very Light
45g to 65g Light
> 65 g Heavy

Good value: Keystroke is very personal but generally, for gaming, a lighter key is preferred.
Noticeable difference: 10 gf
Actuation Force
What it is: The force at the point where the circuit is closed in the switch.
When it matters: This value is not as relevant as Operating Force that is the actual force required to actuate the switch.

When it matters: Whether you prefer a fast and sensitive board or a more secure board with less potential for typos.
Noticeable difference: 0.7 mm
