Ever since the most recent patch, people have been complaining/claiming that their PRR is either reduced and/or non-existent. While smart people would realize that if they suddenly had 0 PRR they would be seeing MASSIVE increases in incoming physical damage, this theory/partial theory has continued to persist.
I did an R5 Bruntsmash incoming damage test yesterday, that I thought pretty clearly outlined that PRR was WAI, but a few people still seemed to claim that they were having issues.
You can view that video at:
https://www.youtube.com/watch?v=5NHBF17c13AEnd result, there was a noticeable increase in incoming damage from dropping PRR.
High with all gear (379 PRR): 280
Low: 176
High missing armor/weapon/shield (173 PRR): 479
Low: 249 (seemed like an outlier, most were ~350)
*Edit: I’m only getting about 5% deviation. Taking the base 379 PRR test, my character is taking 20.88% of damage on hit. Applying that to the average of the test (100/20.88)x230. I get a base damage value (with 0 PRR) of ~1101. Meaning each percentage point of PRR is worth 11 damage.
Removing the low outlier from the 173 PRR test (it’s 100 points lower than the next closest) the average for 173 PRR becomes 383. With the percentage of incoming damage being 36.63% damage taken on hit. 36.63x11 equals 403 damage. The difference between what I actually took (383) and what I should be taking (403) is 4.9%. And the difference damage wise between what I should have taken and did is less that 2% reduction from PRR.
This was the information that I posted on the mobos about what I saw, and tried to break it down. I will admit that Nokowi confused me for a minute when he was talking about 10% difference, and to be honest it took me a while to figure out what he was talking about. He is not wrong when he says that the low number is about 10% too high based on what my low numbers were, but he phrases it poorly. It is about 10% to high in relation to the damage I took. For the reduction to be about 10% less than what it should have been it would have had to be a 100-110 damage difference. The actual reduction difference was about 2% higher than what could have been expected based on what I was taking with 173 PRR.
Today I decided to do a further test after I was told that people had done extensive testing in EE Grim and Barrett and had seen no noticeable increase in damage.

Data of incoming hits for those that don't want to watch a black abashai attack me for seven minutes set to the tune of Post Malone:
20 hits with 354 PRR: 68/90/80/82/83/81/78/85/70/94/82/79/74/83/82/80/75/71/72/87 Average damage over 20 hits: 83.35
20 hits with 180 PRR: 116/122/146/140/136/96/115/151/105/118/109/134/136/139/115/115/121/149/129/140 Average damage over 20 hits: 126.6
Now to break that down:
354 PRR = 77.97% dmg reduction, or 22.03% of incoming physical damage taken. (100/22.03)x83.35 gives 378.34 as a base incoming damage (each 1% reduction from PRR = 3.78 dmg from this test)
180 PRR = 64.29% dmg reduction, or 35.71% of incoming physical damage taken. (100/35.71)x126.6 gives 354.52 as a base incoming damage (each 1% reduction from PRR = 3.54 dmg from this test)
Predicted 354 PRR damage based on 180 PRR test results (3.54x22.03) = 77.98
Predicted 180 PRR damage based on 354 PRR test results (3.78x35.71) = 134.98
To go from what damage I took with 354 PRR (83.35) and what is predicted based on the 180 test (77.98) is a difference of 5.37 damage, or essentially 1.51% more reduction required
To go from what damage I took with 180 PRR (126.6) and what is predicted based on the 354 test (134.98) a 2.2% damage reduction loss would be required. (-2.2%)
You can predict how much damage you will take with a different PRR stat to within a 0.7% damage reduction difference. With this small of a sample size it's close enough to say that PRR has not changed from pre-patch values on given damage reduction, especially considering I use Deific Warding on my tank so my PRR value changes on hit and likely modified the data.
