Hi Tim,?
Sounds like a good schedule. But I wonder if it's better to have the washer conform to the glass surface rather than crush the glass to conform to the washer.
Glass loses it's strength when crushed. And if the glass doesn't conform to the washer, the washer will be at an angle and the nut will apply a lateral force to the bolt. This lateral force may not be much but the result will be an uneven distribution of forces around the washer contact surface.
I think the key is to have the proper torque without destroying the surfaces. I'd rather bend the washer than the glass.
Its possible to level the surface with epoxy putty before applying torque.

Best of luck,
