Missing reps on bench, what's the correct adjustment?

[Tuna]

I've started to miss reps. My last three bench workouts were

161 lb 5 5 5
163 lb 5 5 4 1
165 lb 5 4 3 3

My other stats are

5'10 38 years
37 training sessions
Bodyweight 185 lb (up from 164 lb)

Squat 234 lb 3x5 (up from 110 lb)
Press 108 lb 3x5 (up from 55 lb)
Deadlift 303 lb 1x5 (up from 132 lb)

Squat/Press/Deadlift are still progressing.
(I'll be introducing Power Cleans next week.)

The three questions check out.

I'm looking for advice how to program the bench now. Keep adding weight and complete 15 reps across more than 3 sets? Deload? Try 1 lb jumps (seems early)?

Thank you

How long are you actually resting between sets? Really actually resting, timed with a clock. Other than that, it's probably your bodyweight.
