Also thanks to him for making me find this : )
MORE DETAILS - Technical stuff here:

What happened?
First of all let's look at this cool TNT minecart power formula:
Power = 4 + K * R * 1.5
K = Value between 0 and 5
R = Random value between 0 and 1
Max Power = 11.5
Min Power = 4

K...?
What's K?
K is a variable value that is obtained by most TNT minecart explosion triggers (Fire, Flame arrow, Falling from more than 3 blocks, Collision...)
So you might have guessed already, K is the value that made so much damage to the dragon...but what you probably don't know is that my setup shown in the video uses K = 5 .. (!)

How is that possible?
By stacking 4 minecarts and letting them go for at least 5 blocks, K (for all minecarts) will increase because of the infinite motion trick and reach the max (5)

Why the dragon can't take more than 1 TNT minecart full damage from Power 4-11.5?
Because multiple explosions triggered by the same source are ignored (or they deal normal dmg as a Power 4 minecart)...still unsure what happens on a few rare case..but sadly I never managed to deal more than 75% dragon hp with this

Is the oneshot possible?
Probably, if you can combine this trick twice during a single dragon attack (by attacking it after the first explosion using another tnt cart trap)...but probably not feasible enough for a speedrun
