I would think that this is only true for the Milaanas that don't run hot. On the ones that do run hot, placing the load farther from the heater would be beneficial according to what I've read. User tb42091 has a Mi3 and gets great results doing it that way...
"I cut a screen to slide up in the stem so I could cap it with the given basket screens and to get the load further from the heater. Loaded it up with like 1/2 or 2/3 inch of relatively coarsely ground flower, with absolutely no tamp, and actually a little bit of extra space in the chamber.
I started with a fresh VTC6 and typically had to hold the button for 3 seconds as a preheat, and another 3 seconds to get vapor as I inhale - then modulate from there, often on 2-3 seconds - off 1-2 seconds and repeating that way, inhaling a couple seconds after letting off the button.
I got probably 2 extra tasty wispy hits making sure I wouldnt combust, got like 3-4 really solid hits with really good taste, 1 pretty big hit that was the downturn in taste, and 2 medium hits that finished off the bowl with relatively lousy taste. I removed the stem and tapped it 3 times throughout the session to sort of stir the pack, but when I dumped it out I was pleasantly surprised with how well extracted the whole bowl was, and pretty even too. So my initial impression is, I really like it. 1000% worth the wait. "
He posted a pic of his AVB and its suuuper even. IME, mesh screens don't steal heat from the load. Only dosing capsules do that...
It's almost like people like to use their devices differently based on personal preferences 
and it also seems like, at least with the Mi3, not all are exactly equal. I'm sure there are slight differences in the resistance plus the amount and shape of the mesh in the heater.
