The timing for pallet saves is the exact same as a flashlight save. It's tilts me that every time i see someone try a pallet save they throw it down immediately when the killer starts the pickup animation or when the killer is two or three steps away from the pallet. If you aren't comfortable/familiar with the timing for a flashlight save, just don't go for a pallet save. You are just going to waste a pallet, waste your own time, and hurt your team even more. Practice pallet saves/flashlight saves in a custom game if you want to get better with the timing.
