I don't know if it's a bug or "working as intended", but currently the Earthforce Discipline Quickening focus effect does NOT stack with Tempus Faycite Shard: Earthforce Discipline. The shard says it reduces the timer by 5% but actually shaves off 11.7 seconds. Wearing the chestwraps saves only the 21% of the chestwraps whether or not I equip the faycite shard.
I guess I'll find something else to do with that type 3 augment slot...
