All this build, wrap, wire gauge, wire type, coil resistance stuff is a matter of personal preferences as long as you're being safe.
Just me, after trying almost every combination under the sun, Ka 2 strands twisted is by far my favorite 'coil build' type for what I consider the ultimate in vape quality.
The exact same .6Ω build can produce vapor from almost cold to cool to warm to hot enough to burn flesh with a 2 second button press. It is all about understanding why, how and most importantly when to stop.
Everyone has different sense of taste & what they define as vape quality, no one can tell you what you'll like best.
You have to know what you're doing & why, you'll figure it out, it takes time & patience.
Jumping in over your head trying to figure out how to skip steps, rushing to squonk by Tues is a recipe for at least disappointment, worst case danger.

And I have asked how can you tell your going to push to many amps to the coil
I get 3.7/ohm= amps as long as I'm not going past 30 what my ijoy are I'm good no?
I always test on my paranormal alien ohm meter and now my drag usually go to the shop when I rewick orslap new coils on mybreload
Step 1: measure the coil
Step 2: do the math (amps = 4.2 / ohms)
Step 3: compare the result (amps) to your chosen cell's discharge limit. Is it less? Good. Wick it, vape it, tell us how you liked it. More? Stop, start over, try again with more wraps or thinner wire.
It has been said many, many, many times before.
When using a mechanical, use the full charged 4.2v when calculating amp draw.
Because you seem to be very confused maybe using a very simple ohms law calculator would make thing easier.
---> Watts/Volts/Amps/Ohms conversion calculator
Enter 4.2 in volts column, then enter the actual measured total resistance in the ohms column, then click calculate. Do not enter any other value just 4.2 & Ω.
No, if you draw the full CDR of any cell you use you're leaving no room for any errors or oopses.
When first starting out and especially due to the fact your seem to be struggling with the basic first steps of using a mechanical it would be safest to stay under the CDR of your cell.
If your are asking for my opinion, I suggest staying well under the CDR until you understand what you're doing, say in the area of 18a to 20a max using a true 30a CDR cell.
Vaping near to or at the CDR of any cell is something only folks very familiar with, a full understanding of mechanical use and confident in their abilities.
The above meant not to be rude or belittle, only an attempt at keeping you safe.

You didn't mention the diameter of the coil, which makes a difference as well.
24g ni80 8 wraps with 4mm diameter = roughly 0.7 ohms
24g ni80 8 wraps with 2mm diameter = roughly 0.4 ohms
I think you said you were using dual coils, so the 4mm coils are probably going to be safe for nearly any battery, but the 2mm coils are going to be a bit above 20A, thus a bit too much for some batteries. Of course these are all ESTIMATED numbers and are no substitution for measuring the final result.
3.0id each coil with 13mm leg length said .606 when I put 7 mm leg length it was like ..56
I been tinkering with vape tool today
I got ijoy 20700 5 legs so it's 30 amps .2s don't even get near 25 so think it was like 15 to 19 amp if say .22 was the ohms
So most of my builds will be under that I don't be doing .15 or .09 builds as that goes closer to 30 amps which the ijoys are and I don't want to stress the battery

13mm legs are mighty long legs (for a coil that is). A "leg" is defined as the length of wire between the coil and where it makes contact with the post. Legs usually aren't more than 1-3mm long. Depending on the deck and coil diameter of course.
You're gunna need a Really BIG RDA to use a Coil with a 13mm Leg. Because 13mm is about 1/2 Inch.
Just do yourself a favor. And Build a Little Higher Ohms to start off. At least until you get more Comfortable with the Entire Mech/Amps/Ohms thing.
You are not making any sense with this post,
I don't know of any RBA that 13mm or 7mm legs would fit in.
You want to use dual coils, right?
2 coils .56Ω with 7mm legs which is basically impossible to use = .28Ω
When you trim the legs to a useable length the resistance will drop/be lower which is the wrong direction to go.
You have to be sure, not guess or estimate, your resistance has to be measured accurately.
Modeling coils with unusable parameters is a waste of time & most likely confuses you further, or worse, gives you a false sense of security.
4.2v / .22Ω = 19a
4.2v / .2Ω = 21a.
Why would you build under that?
4.2v / .15Ω = 28a, too close to your cells 30a CDR for someone struggling to grasp the very beginning basics.
4.2v / .09Ω = 46.6a, ridiculous & dangerous.
When using a mechanical with low sub ohm resistances words like, should be, around, closer to, I think all should be checked, measured & verified into I know, before you press the fire button the first time.
Like I said i was playing with lead length as I don't really know what to put there in not going to do a .1 build if ever
So is there a way to tell if coils going to have huge ramp up or a cold vape?
Giant coils slow ramp up. More metal slower ramp up. Honestly that simple.
No there is no multiplication involved. And wattage is immaterial to using a mech.
If you expect to duplicate the warm comfy vape you get with dual claptons that you dial in just so on a regulated mod I'd say forget it. You need to get the basics down before even attempting that so just make believe that doesn't exist for now.
If your tank shows up today just follow the advice already received in multiple posts in the 6 page thread and throw some simple round coils in around 0.4-.5 ohm and see what happens. Vape it for a few days then come back and ask about how to improve on whatever you feel is missing. All you're doing is confusing yourself and us at this point.

I agree with your whole post, except for this statement. His formula to calculate wattage IS correct (Voltage squared / resistance). However as you and I have both pointed out, there is no need to know wattage with mechs.
I do feel confused... But not about Ohm's law anymore, thanks to this thread, so I am shelving my momentary annoyance with the OP and am merely hoping he starts to get it.
Everyone seems to assume that the mech experience has to be "better" immediately like a genie from a bottle or something. I can pretty much guarantee that it has a learning curve and that the first time I build mine, the vape will probably be weird and suck. If I go in expecting that a) I may be pleasantly surprised b) I will know I am building for SAFETY not effect. SAFETY first, and effect later when I find my feet.
You don't really think that trapeze artists at the circus start out at 100 feet up and without nets, do you? You do realize trick skiers actually start out with an artificial ramp and landing into a deep pool of WATER (yes with skis ON) while learning to find their eye triggers that tell them how to land and etc?
What I do NOT understand is the failure to accept that safety comes before effect. You aren't going to get ANY effects if you don't practice safely first. That's a lot easier to absorb than Ohm's law, but this is where the OP seems to be having difficulty. If you build a SAFE build, you can then go on to work on vape skills. That easy.
