I'm using the WorldTickEvent event if that affects the answer.

Not sure what you are asking...

but there are 20 ticks per second.

Actually, thanks to the power of my key board's metronome, I've found out the world gets updated 40 times each second.

Probably once on the client and once on the server: 40 / 2 = 20.

It's doing the counting server-side. I'm pretty sure, I registered the event in my ServerProxy and I have a !world.isRemote check.

Hi

 

At a guess, you're probably counting both the pre ticks and the post ticks.

("Phase = start", "Phase = end")

 

    public static class WorldTickEvent extends TickEvent {
        public final World world;
        public WorldTickEvent(Side side, Phase phase, World world)
        {
            super(Type.WORLD, side, phase);
            this.world = world;
        }
    }

from

    /**
     * Every tick just before world and other ticks occur
     */
    public void onPreWorldTick(World world)
    {
        bus().post(new TickEvent.WorldTickEvent(Side.SERVER, Phase.START, world));
    }

and

    /**
     * Every tick just after world and other ticks occur
     */
    public void onPostWorldTick(World world)
    {
        bus().post(new TickEvent.WorldTickEvent(Side.SERVER, Phase.END, world));
    }
