Questions and Answers
Q: What factors affect the calculation?
A: Weight of the bb: This is one of the most important variables. Measured in grams.
The bb's speed measured at muzzle: One of the basics of the measurement, measured in m / s.
Density of air: We have chosen 1.2 kg / m3, which corresponds to about + 20C and 0-50% humidity.
Air resistance coefficient: A number between 0-1 that tells how much air resistance the bb gives cause of. For a normal bb we have chosen 0.4 as a reasonable value.
The diameter of the bb: It is possible to calculate for all the different diameters we have created the table with 6 mm as a foundation.
Earth's gravity: 9.81 m / s ^ 2

Q: Why can't you just continue to use VSAF? Isn't this the same thing?
A: Old VSAF The table does not take into account that a heavier bb retains it's force longer than a lighter one.
This phenomenon we call "JC2 Joule-Creep type 2" #2020tabellen is calculated on each ball weight and what impact energy it has on hit.

Q: 1.2J at 0 m safety distance? Isn't that much?
A: If you look at some of the examples in the previous question, you have been hit under the VSAF table but much higher limit than 1.2J.

Q: On my CQB field I want to keep the limit of 1J. What can I do?
A: #2020tabellen has a category CQB1 that has 1J as the limit. The organizer decides which of the classes CQB1 (1J) or CQB2 (1.2J) should apply to their particular field.

Q: If I play with 0.28g bullets in the Assault 2 class, will I not have a worse starting point than someone who plays with 0.36g in the same class, since my bullet loses power earlier?
A: It is true that your bullet of 0.28g will have lower impact force than a bullet of 0.36g at the same distance. It has nothing to do with the MOD chart but is a physical reality.
As we safeguard the safety within safety distance as well, you must not exceed 1.7J at the muzzle, which would be required to get the same range with a 0.28g bullet.
