Okay, done with the test on the 28ga build.
How many 4 second puffs and how much electricity it took to get through 5mL of 70%vg. All coils set to 66.6 Watts of heat.
All coils had 4mmID, 8.4mm width
Exception being the 30ga Radiator which had a more streamlined shape but an effective 4mm ID.
For comparison:
26/32ga fused Clapton: 195 puffs, 51,948Ws
26ga parallel: 158 puffs, 42,091.2Ws
28ga parallel: 134 puffs, 35,697Ws
30ga triple parallel: 96 puffs, 25,574.4Ws
