Hi

Maybe you should consult the "Jaws: Masseter Pattern Vs Temporalis Pattern" thread. In my opinion after reading many ideas and techniques about mewing and orthotropic on this forum I came to the following conclusion. There is no universal mewing but actually two main forms of tongue/muscle posture : Engaging the Masseter or the Temporalis pattern. By jutting the jaw like biting in something, my tongue can't touch the back of my palate ; even with suction hold ; it's nearly impossible. I feel my masseter contracting the more I jut my mandible forward with abolutely no Temporalis activation. 

On the other hand, one day, I decided to make the strongest suction with my tongue to the roof of my mouth (especially the back) In order to make contact with my tongue to the sphenoid bone. So I tried, and naturally, my tongue stretched forward (touching my upper incisors and lower lip), my mandible retracted, temporalis activation at it finest and no masseter contraction. 

By the way, I am convinced that the temporalis pattern is the one to priorise for the resting tongue and digrastic muscles. However, despite the fact that I feel all the corrects mewing sensations (tongue all the way to the roof of the mouth and applying pressure on the side), my mandible setting back give me a strange face, like I have a slightly recessed chin and overbite. 

By sharing my experience, I hope it will be useful for some of you ! And if others have answers to my issue... 

@remy

Yeah but I am having a problem where my Massaters are contracting against my will. This happens especially when Im stressed. It's a psychological thing obviously I need to work on.  Maybe I should try meditation or something to reduce stress

@remy By the way did you get the results promised from Temporalis pattern in that thread like shortening of the face along the temporal-palate axis and relative decompression of the masseter-zygomatic axis?
