i think it's got to do with the insufficient high temp , or the short pressing time. what parameters and furnace are you using?

usually short and rounded margins are a result of shortage of heat or heating time.
gc investment is great , so i don't think it's the cause, if handled right.

Yep, you're right....increase high temp
