14 cannons spawned, and 8 or 57.14% of these broke due to Gods Attention or some other unfortunate and cacophonous calamity. The other 2, or 14.29% were dispatched by a player!
The cannons shot 16 balls at Jonny. They jumped over 7 or 43.75% of them, while an additional 6 or 37.5% of the balls fired missed completely due to our faulty aiming system. The other 3 or 18.75% were direct hits.

Also, a total of 7 rock throwers spawned, and 1 or 14.29% of these broke because... I think they were just too stupid to get out of the way of the pit. Or maybe, God hated them!
The throwers shot 25 rocks at Jonny, hitting with 0 of them which is about 0% of the time. The other 25 or 100.0% of the rocks missed them because I think that these damn throwers are blind or something. Like can't you guys aim?
The player grabbed 9, or 36.0% of all the rocks that fell.
They threw 7 rocks. 7 rocks hit cannons, whereas 0 missed. As a result, Jonny's accuracy was 100.0%!

In the end, it was a cannon that killed Jonny
