@PhoenixMiner - please research a bit the stale problem. With 2.5d i get 3, 4 even 5 times more stale vs. 2.4. Smiley Anyway, the miner is amazing, getting 6 mhs more from 192 to 198 mhs with 6 rx 580. Good job.
Also, please add to the miner cclock, mclock, cvddc, mvddc and other commands from Claymore, it would be really awesome.

can everyone please check effective hashrate on the pool side?

its relatively easy to have the excavator SAY you're running X MH/s, but if you aren't submitting shares consistent with that value, it doesnt matter and you will be paid based on a slower rate. this is what i experienced. I dont think anything nefarious is happening, and i like the communication from the dev thus far, but everyone should be diligent in tracking their ACTUAL performance vs what's reported.

in my case, over a 24hr period, Phoenix said it was running 2-3% faster, but submitted shares on nanopool were actually 2-3% lower than with claymore. I've switched back to claymore for now, but mainly ONLY because of the lack of tt and clock adjust functions. when those are added and the miner matures a bit, I'll give it a second shot.

24hours is way too little to make any measurements, you need 4-5 times that to get a good picture - From my experience phoenixminer, even the 2.5d is giving me more shares per day on ethermine compared to claymore, I actually have a machine with 12xRX580 which consistently underperforms with claymore miner, giving me fewer shares per hour than it should, on phoenix that machine runs smooth as butter.

V2.5d appears to have some stale share issues, it is actually leveling out a bit for me, but are still producing about 50% more stales compared to 2.4 - But 2.5d solves a problem which I have been having on one of my machines so overall there is improvement to track.

The DAG epoch changes in that time span.. it invalidates any comparison as whatever is run for round 2 will inherently be slower/less shares slightly that if it were run on round 1
