Changing between MTL and DL

[xCH13Fx]

I think all the settings are pretty intuitive, but what I don't understand is, how do i know if my device is using the MTL or DL settings? 

I wouldn't imagine it can know if i have airflow open or not, so how do I know exactly which settings are being used?

Is there any difference between the two settings in reality? Meaning if I make the settings exactly the same for both, is there any advantage to using one over the other?

I'm using the basic 'best' settings I found in here, 0 boost, 1 warmth, default watts. 

Another thing i noticed, under 'Mod' --> 'Atomizer' I noticed that the max resistance on DL and MTL seems to be correlated to the .25 and .5 pods respectively. Is this how it knows to use MTL vs DL? Meaning if i put a .25 pod, it'll use DL settings, If i put a .5 it'll use MTL? 

Lastly, anyone have better airflow experience with the third party drip tips? The airflow on this things is pretty weird. 

Thanks!

.25 is DL and .5 is MTL..... yep the device knows which one you seat....
