Advance mixer power coils?

[Arkhainn]

I have one or two (depending on machine) of each machine with 24 advanced coils, which is the maximum, several with 12 and a few with none.

In most cases (when a recipe requires little or no power) something between 6 and 12 advanced coils will give you the best bang for your buck.

For recipes that use a lot of power you may want to over-power it more, for the crafting time and spark discounts that others have mentioned.

The unpowered machines I generally only use for recipes that have no spark cost (like refining stones, for example).

Let me find the last post I made with my testing on this to give you an idea of the numbers involved, will edit in a minute.

Edit:

@Arkhainn

I only own advanced coils, so I can’t confirm how much per 100 power, only per 300 power.

I have a table (percentage in relation to the 0 coil cost) for the refined titanium mass craft as an example:

Adv. Coils	% of Total	Time (seconds)	Spark
0	100.00%	3000	20000
1	76.62%	2298	15323
2	69.69%	2090	13938
3	64.05%	1921	12809
4	59.51%	1785	11902
5	55.94%	1678	11187
6	53.17%	1595	10633
7	51.08%	1532	10216
8	49.55%	1486	9909
9	48.47%	1453	9693
10	47.73%	1431	9546
11	47.26%	1417	9452
12	46.99%	1409	9397
13	46.84%	1405	9368
14	46.78%	1403	9355
15	46.76%	1402	9351
16	46.75%	1402	9350
17	46.75%	1402	9350
18	46.75%	1402	9350
24	46.75%	1402	9350

As you can see, after you hit the 50% mark the diminishing returns kick in pretty heavily. Still worth to go up to 12-14, particularly for recipes with large spark costs / long crafting times (like shop stands for example).
