Since ravenforum.org keeps crapping out... I guess I'll just post the in progress test details here:

Pool / Stratum Difficulty Testing:

For this test I used a single 12 GPU 1080Ti rig on Windows 10, split into three mining instances. All three mining instances were balanced to get as close to the same hash rate as possible. Each mining instance is running at the same time on the same machine mining on the same pool.

All three instances have intensity set to 21, GPU target power set to 100%, no overclocking.

The instances/rig are managed by Awesome Miner, which restarts the miners for various reasons, based on rules I set.

The plan is to do three rounds of testing, each round lasting approximately 10-12hrs, at the conclusion of each round I'll rotate the miner to a new instance, until each miner has had a chance to run on each instance. I'll also normalize the results to averaged blocks found per round.

Miner tested:
Enemy 1.08 - 1% dev fee

Testing:

Variable Diff / pool set diff
d=50 (2/3 of my avg hash | i.e. divide hash by 1.5)
d=36 (1/2 of my avg hash | i.e. divide hash by 2)

Why?
I've seen people in various Discord channels recommend setting a static pool/stratum diff. Typical advice is to set it to your avg hash divided by either 1.5 or 2... So, I wanted to run a test to see if it really mattered.

Results:

Round 1 - 128 Blocks Found - Duration: 661 minutes (var diff 1 restart, accepted not increased in 4 mins)

[Instance 1] Normalized: 195.95 RVN / 177.88 RVN - Var Diff - Pool Link
[Instance 2] Normalized: 188.81 RVN / 171.40 RVN - d=50 Pool Link
[Instance 3] Normalized: 193.05 RVN / 175.25 RVN - d=36 Pool Link

Round 2 - 135 Blocks Found - Duration: 696 minutes (var diff 1 restart, accepted not increased in 4 mins)

[Instance 1] Normalized: 191.57 RVN / 183.42 RVN - d=36 - Pool Link
[Instance 2] Normalized: 199.23 RVN / 190.75 RVN - Var Diff - Pool Link
[Instance 3] Normalized: 194.54 RVN / 186.26 RVN - d=50 - Pool Link

Round 3 - 160 Blocks Found - Duration: 727 minutes (var diff 1 restart, accepted not increased in 4 mins)

[Instance 1] Normalized: 171.94 RVN / 195.11 RVN - d=50 - Pool Link
[Instance 2] Normalized: 165.06 RVN / 187.30 RVN - d=36 - Pool Link
[Instance 3] Normalized: 169.83 RVN / 192.72 RVN - Var Diff - Pool Link

Normalized Average Results FINAL

#1	*	\| Var Diff	\| 188.34 RVN
#2	-1.55%	\| d=50	\| 185.10 RVN
#3	-2.82%	\| d=36	\| 183.23 RVN
