Before we get any issues here, we need to consider a couple of things:
1) finding the "right" embouchure is NOT the key to high notes or even playing trumpet. I see a tendency here at TM for especially young players to blame the embouchure for everything and that is PLAIN BS. They play crappy because there is no structure in their approach
2) teachers that teach "embouchure" are often doing NOBODY any favors. Young players that get a healthy daily routine early very often gravitate to their natural best playing. The upstream students that I have had, generally got a tip to hold the trumpet differently, without me going into detail why. I really consider it important when you are in your development stage to carry as little ballast as possible. only reading or understanding half of something makes the information dangerous. That is why I absolutely refuse to patch embouchures over the internet. The dummy that assumes because they have no double C that their embouchure is bad has a big chance of trashing the little that they have with an embouchure that is even less suitable.
3) it is generally good regardless of embouchure, to tuck the chin in some. See the body use tips here: David G. Monette Corporation
The players with different embouchures will point the horn relative to the lips and jaw, not the tucked in chin.
My standard method for new students is to get the breathing and body use together first. After that a daily routine is a GREAT low impact way to discover things. Relatively small changes tend to give the best results. We are not talking about inches and 45° difference in angle between these "embouchures". The fine tuning can be as easy as not putting 4 fingers between the third slide and bell, rather two up two down or in extreme cases 1 up 3 down. I find a much bigger difference in what we do for articulation exercizes.
Again, this is stuff for a qualified teacher. The chance of getting it right with DIY is practically zero.
