How much do you add to the bar each workout? Are your other lifts going up? If you are missing bench due to time sometimes, do you also miss deadlifts? How about presses and power cleans (or whatever you do if not power cleans)? If you are still increasing weight on the bar each workout, I'd keep going with what you have. If you are looking for programming changes to help, I think the time-restriction might be the thing to look at so that your lifting is consistent, even if not the ideal schedule.
Beyond how regularly you are benching, have you considered form, sufficient calories to drive growth, rest between sets, and sleep?
