I have some questions on the ratios for a FB DMT Vape cart.

I have been attempting to work out the math. I would use PG and FB DMT. Even if I were to have a 3:1 mix, strong-sided, would it not take 8 normal hits or 4 2x(large) hits to reach a breakthrough? To my understanding, it takes somewhere from 20mg to 40 mg to experience a breakthrough. I settled the math at 30mg dosing. on a 4.2v pen you inhale roughly 5-8mg per hit at a 3:1 ratio is 3.75-6mg of dmt. (the math ((Ratio)*temp burn amount)*hits=dmt dosage) ((0.75)*0.005)*8=0.03mg. How do people get by with a 1:1(((0.50)*0.005)*12=0.03))? is a 2:1 even any good((0.66)*0.005)*9.09090909-=0.03? how is a cart enjoyable? would it not make more sense to always just use a pipe or other form of administration? 4 large hits or 8 normal hits seems excessive to me and that is the minimum?

The calculator says you can mix a 1:0.5 Ratio and it still be soluble in PG.

Though I've no experience of Vape Pens / Cartridges, only Vape Tanks on full Vape Mod Boxes, though I appreciate that Vape carts need to be stronger.

Just my personal opinion but I'd not get caught up in how many Milligrams you NEED to put in yourself for a specific depth of experience, we are all different and a well hit 5-10mg from a Glass Pipe can take me to what I'd say is the Waiting Room or maybe spirals of symbols and hints of jester faces.

Also consider small pre-load hits before a bigger hit, its a bit like warming the Car engine up before driving like a Tw@ at full speed.
 
Like @TransistorBass I also use rebuildable tanks on battery mod boxes, based on mintylove's YouTube videos, rather than prefilled carts that I've no experience of.

I have gradually made my juice weaker, settling around 5-6:1. I have never needed more than one hit. I found very strong mixes hard to dose because you'd require such a short hit that minor variation could result in a very very strong dose from a small overshoot on fire time.

You must remember that d-juice from a modern RDA/RTA and emesh are stunningly efficient methods of getting DMT into the lungs compared with flame based methods that potentially burned some in the process. I suspect therefore that you should base your math on the lowest dosage in each range, i.e. 20mg for breakthrough, not 40.

It is helpful to make sure you are directly inhaling deep into the lungs, and again, I find a weaker mix and correspondingly longer inhale facilitates this. I also think hot vapour is more potent but some dispute this.

Extract yourself, get a good mod and tank and start around 4:1 and you can always go stronger later if needed. That should enable you to dose based on fire duration and the exact milligrams will become of academic interest only.
 
would it not make more sense to always just use a pipe or other form of administration?
Yes, I think so, although that's probably a matter of preference. I think carts are popular due to them being highly portable and convenient, not due to them being particularly optimal. For e-juice, a sub-ohm setup works much better: A 2026 sub-ohm e-cig setups guide for DMT e-juice vape
Good carts are less prone to leaking when transporting them than pods, and also smaller. But I would say that's their only advantage.
