IMHO, 0.10ohm will not be OK on a mech period. I actually tested this a while back, (without using an actual mech because I like my face where it is). Thread got past 7 pages with at least one full on flame war in the middle. It’s totally unreadable.
The digest version is small non scientific grade ohm meters don’t actually measure to a hundredth of an ohm, they just read out like they do. The actual reading will vary by a few hundredths to either side. If you’re above even 0.2ohm this doesn’t matter much, but as you approach dead short (which 0.1ohm approaches) that few hundredths of an ohm starts to really matter on a single battery mech. I put in a pair of coils preset and mechanically measured to be 0.1ohm. My meter read anything from 1.16 to 0.6.
If you want to vape those coils it can be done, but you need a large powerful device in order to make sure you have enough safety margin. I used a legend with high drain LG Browns. It really was a nicer vape than I was expecting.
