GS Trigger question:

I am one hour below the GS trigger and was awarded a GS. The pay for the trip equals 10:30 in the activity section of time card and the GS pay part shows 9:30.

I believe this means I will only receive 20 hours of "total" pay instead of the 21? I understand I can use my bank but I am negative 30, so thats Moot.

Just want to make sure I get "some" of the GS pay, instead of nothing until I hit the GS trigger. Thinking it's a equal reduction in GS pay for each hour underneath the trigger….

experts?
