If we average out all of the days, regardless of moon phase we get:

Darksday 38.89%
Earthsday 18.06%
Firesday 29.86%
Iceday 39.58%
Lightningsday 24.31%
Lightsday 16.67%
Watersday 24.31%
Windsday 21.53%


From this we can conclude that Iceday and Darksday gave the highest results, and Earthsday and Lightsday gave the lowest. We notice Darksday and Lightsday are at the opposite ends of the spectrum. We must also note that Wind is weak against Ice, and is strong against Earth. The results reflect this relationship.

Moon Phase

If we average out all of the Moon Phases, regardless of days we get:

Full Moon 18.49%
Quarter Moon 21.88%
New Moon 39.58%


From this we can conclude that New Moon gave the highest results, and Full Moon gave the lowest results.


So if we follow the indicators, our best results should be on Ice/Darksday on a New Moon, and our worst results should be on Light/Earthsday on a Full Moon. Pulling from the data above we get:

Darksday New Moon 58.33%
Iceday New Moon 56.25%
Lightsday Full Moon 12.50%
Earthsday Full Moon 12.50%



For the sake of comparison:

Darksday New Moon 58.33%
Darksday Full Moon 27.08%
Lightsday New Moon 25.00%
Lightsday Full Moon 12.50%

From this we can conclude that Iceday and Darksday gave the highest results, and Earthsday and Lightsday gave the lowest. We notice Darksday and Lightsday are at the opposite ends of the spectrum. We must also note that Wind is weak against Ice, and is strong against Earth. The results reflect this relationship.

These are the results. It isnt spelled out for you but the information is contained there.

I still dont think you understand that I did the same synth, same crystal, thousands and thousands of time. I didn't ever stop to craft all on new moon, or the proper day the first 15k. I did face directions, I did note the days/moons or really bad and really good runs. It wasnt until I understood it that I finally moved to another synth with much more expensive base mats but a much higher HQ profit margin. And did that one 10kish times, for quadruple the profit. Even then I would still craft when I needed money and I could notice the difference.

Edit:
Just to note, I've done about 2400 synths here, at base NQ thats 720k, if 50% HQ1, thats an extra 360k, if 10% HQ2 thats an extra 216k, if 5% HQ3 thats an extra 144,000. All in all it has been probably about 1.2mil so far. 2100 before the change 300ish in the last 7~ days since I came back.
