Maybe someone else can chime in here. I'm not used to comparing full-ROM CGP to regular flat bench. I'm partial to partials for those.
Judging by the level of your lifts, I'm gonna have to say that you just need more time under the bar. Pay close attention to your form and keep adding weight. You've got good, tried-and-true lifts in your program and I don't think there's much danger of your chest lagging too far behind your triceps, so just keep plugging away and things will get better.
