Can someone explain a few things to me?

G/S trigger? This is only for REG right? And REG won’t receive double pay until their accumulated credit reaches the G/S trigger?

GS on reserve? If it’s on an X Day then you’ll reserve single pay no credit above guarantee (and a PB day)? If it’s on an on call day all you receive is credit towards your guarantee?

IA is always single pay above guarantee?

Is there any pay difference between a OOBGS and a GS?
