here's my theory why MTL needs less flavoring.
Typical MTL draw is 35ml. Lets say, I'm vaping at 7 watts, and my coil produces X amount of vapor. So, the concentration is X/25.
Now, Direct Lung, at 20 watts, since vapor production is proportionate to power, there will be 3*X vapor compared to MTL.
Typical inhale volume is 250ml, hence vapor concentration is 3*X/250 or about 3 times lower compared to MTL. Possibly even lower since direct lung draw is usually shorter.
