Any other suggestion you folks have that would help if we want to strike the barrier mirror which become crucial to get good scores in LSS.
Also, I heard next year, optics is going away, any idea with which event this would be replacing?
No, removing the barrier mirror should not be allowed. If you're having trouble measuring the barrier mirror's angle because it moves, you're probably allowed to just hold it in place so that it doesn't move. It should be especially easy if the LSS has a magnetic surface to hold the mirrors in place. If it's hard to put a protractor on the surface of the LSS because other mirrors are in the way, you can just place it on top of the barrier mirror, making sure not to move it. I've seen a lot of people use protractors with strings attached to them to help them measure the angles.

Next year, optics should be replaced by circuit lab.

Hope that helped!

Does anyone have a big chart for color mixing? We have the basic color mixing diagrams from the Wiki, but we have come across many questions about tertiary mixing and/or a combination of additive and subtractive mixing. If anyone has a concise reference to study for that, it would be super helpful.

in division B Lasershoot, can the mirror on the barrier be on the back side of the barrier?

The mirror can face any way.

I would expect the mirror on the barrier to be facing away from the laser.

At the competitions I've been to, that hasn't necessarily been the case. The barrier mirror has been facing the laser more often in my experience.

It could technically be facing the side walls.....

Of course if the barrier mirror is facing the laser, it's not much of a barrier
