Incidentally, Ansco 130 will develop your paper even if the glycin is dead when you mix it. It is essentially dektol with glycin and more bromide added.
I've added glycin to homemade dektol lots of times. It makes it last longer. And it makes the development slow down at the normal "done" point but actually keep going in the midtones without just fogging the paper. So, you can leave the paper in for 3 or 4 extra minutes and see some difference that might be an improvement.
In what proportion have you added glycin to dektol?
