Nexus Clash

I've been tossing the same rock at the same targets for quite a while now and been consistently disappointed.

Listed accuracy of the rock is 75% in my dropdown.

Base accuracy is 25%
Rock itself has a +10% per the wiki.

The character (clash.php?op=character&id=12) has had, the whole time this was going on,:
Ranged Weps, +20%
Thrown Weps +10%
Adv. Thrown weps +10%

This all adds up to 75% as well

I checked my history when I'd thrown 200 times or so and it was a disappointing 64% hit rate. Now that i am at almost 400, I checked again.
394 attempts, 255 hits: 64.7% accuracy. This isn't bad luck anymore. It's definitely centering around a different mean than the game and documentation say it should be.

It's possible targets have a defense rating though - it'd be mean, but it's possible. This message is a reminder to my future self to go do that.

Tbh I thought they had -20% d like doors and wards, but that's not borne out by the data.

What kind of dodgy bottles are you throwing at?
