Should I apply or retake?

So I was averaging 174 in PTs and ended up scoring a 169 on the October test. The only other 169 I scored in the three months leading up to the test was while sitting in the middle seat on a flight. I am confident I can score better but how worth it is waiting an extra year (I would retake in June and apply in the following cycle) to hopefully score higher? Should I apply this cycle and see what happens or wait? Also my GPA is 3.68. Any advice is appreciated. Thanks!
