How do the Arena Weapon Spawns Work?

So basically, I’ve been messing around with customs trying to get an idea of the weapon timers to help know when they were going to spawn.

Low tier pickups (BR, Carbine, SMG, Grenades) seem to all be on 30 second timers after pickup.

Power-Ups respawn after two minutes.

Power Weapons (especially on pads) seem to have thier own rules though. Sometimes the countdown kicks in straight after pickup. Anyone sussed out the specifics?

Regular pickups are 30 sec as you said. Power ups are every 2 mins. Weapon pads are 2mins after despawn or 3mins after despawn for precision weapons.

edit: to clarify, if anyone is still holding sniper a weapon pad won’t spawn a new one until 3 mins after its despawn
