The reason your readings are so messed up is because your coil has a short. This will cause erratic readings in resistance & hot spot(s) that will produce an extremely unpleasant vape.
I'm going to agree single coils are better to learn with, for the simple reason of there's less to mess up. With dual coils, not only do you have to wrap 2 identical coils, mount them identically, make sure none of the leads are shorting out the other coil, and (for contact coils) make sure they're both squeezed equally... But you have to try to wick them both exactly the same so you can learn proper wicking. Overall there are more possible problems and troubleshooting is a little harder with dual coils. With a single coil, you just worry about doing it once. If something goes wrong, it's easier to figure out exactly what, why, and how to fix it. Coils glowing on the edge? You either have a messed up wrap, hot legs, or a hot spot (or all 3

). Coils glowing in the center? Probably a wicking problem, but your coil could be too small diameter wise as well. A hotspot is also possible, but much less likely and it would be obvious from how it looks when fired.
Also, parallel coils are hard. I don't mean hard like practice a week and you got it, I mean even people that have perfected their skills still mess up coils occasionally. Since two wires are running parallel, having a contact coil is pretty much required, which means those two wires have to run EXACTLY parallel to eachother while maintaining perfect contact with the wire on either side... And those are just the problems you have while wrapping it, which is by far the easy part. Save those for after you've perfected your single coils, perfected your dual coils, and played with a few harder builds (Diamond coil, vertical coils, claptons, etc.).
Just a small tip for you as well: Try to adjust your coil as little as possible once you mount it. To minimize adjusting, try bending the leads so all you have to do is hold your mandrel in the coil and pull the leads taught through the post holes to mount it. Small adjustments like pre-bending your positive lead to the bottom center of your coil for a center post build (like what looks attempted in your parallel build) and the negative lead out so it'll slide right into the post can make things a whole lot easier, ESPECIALLY when it comes to the harder builds (like parallels). Needle nose and those small curved pliers are amazing for this
He's not quite ready for sleeper builds

Let him learn how to wrap a proper coil normally first

Also, I think you meant continuous builds... Sleeper builds implies a specific wire, gauge, coil, and wicking method. Rip trippers was an idiot when he made the video that confused everyone

E: Wow, didn't click the video to see it was rip trippers til after I wrote this comment... Didn't mean for that to come off as aggressive, I was just making the comment in general not knowing that's what you linked xD
