Summary0014311: Quaking affix algorithm not correct
Description1) Bug description

The quaking algorithm on this server is: Do quaking every 20 seconds.
However, the algorithm instead should be: Every 20 seconds there is a chance of quaking.


2) Proof: Official server video

Example video from official server: https://youtu.be/26fm5wxVhCI?t=63
(Note that timestamps are not the actual video timestamps but remaining time for the dungeon timer.)

Quaking at 34:10 dungeon timer remaining
Quaking at 33:50 dungeon timer remaining
No quaking at 33:30 dungeon timer remaiing
Quaking at 33:10 dungeon timer remaining

In this example you can see that a quaking had the chance to happen at 33:30 but it did not happen.


3) Proof: Argusx100 video

To show that quaking has a 100% rate on this server, here is the first part of an Argusx100 Cathedral key: https://www.youtube.com/watch?v=cLzKD6I3qwo

These are the timestamps (remaining timer) for quaking. You see that it happens every 20 seconds.

4) Correct Algorithm

What is the chance of quaking to be triggered on the official server at 7.3.5?

I haven't found a documentation. What I did instead was to collect warcraftlogs.

I've picked 17 logs containing the quaking affix with the following requirements to make the research easier:
- The player has not died during the dungeon (as a dead player can't have quaking debuff)
- The dungeon does not contain scripted sequences where quaking is never triggered

Then I did the following math:

How many seconds does the dungeon last? Example: 1459 seconds
How many "20 second" intervals does it have? Example: 1459 / 20 = 72,95 => Take Math.Floor => 72
How many quakings did appear? Example: 55
=> The avg. quaking rate is 55/72 => 76%


For all 17 logs the avg. quaking rate turned out 77%

I understand that 77% might not be the real chance of quaking as 17 examples is still a pretty low amount, but the real chance must at least be close to 77%.

Therefore I suggest to change the current quaking algorithm from "Do quaking every 20 seconds" to "Every 20 seconds there is a (close to number 77)% chance of quaking to be triggered"

Here is the warcraftlogs data I've used.

The format is:

Link
Player name
Total dungeon time in seconds
Number of 20 sec intervals
Number of Quakings
Quaking average (Number of quakings / number of 20 sec intervals)
