How can I adjust the tolerance parameter for pdeadgsc from adaptmesh?

I am trying to use adaptmesh to solve an elliptic PDE, and I would like to use pdeadgsc as the triangle selection method. Here is an example of code:

[u,p,e,t] = adaptmesh(g,pdem,c,a,f,'Mesh',p1,e1,t1,'Tripick','pdeadgsc')

I pass an initial mesh to the function for refinement. But when I run the code, it does not refine the mesh. It just stops immediately and says "adaption completed." When I use pdeadworst, it refines the mesh as intended.

How can I set the tolerance parameter that is used in pdeadgsc?

If I am not mistaken, you can set the 'Par' name-value pair to something less than 0.5 to have the effect you want.

Yes, I thought the same thing. However, it has no effect. This function call

[u,p,e,t] = adaptmesh(g,pdem,c,a,f,'Mesh',p1,e1,t1,'Tripick','pdeadgsc','Par',0.05)

simply terminates after the first mesh generation with the message Adaption completed, regardless of the value of Par (0.5, 0.05, 0.005, etc).
