static versus dynamic

[bruno]

I started training for freediving in september. My time in static was 3 min (best) and now i'm doing 4 min without problems (4.25 best), which in competition would be 45 points.

my dynamic was 50 m with fins, now it is 66( best), which in competition makes 33 points

In comparison we get 45/33 = 1,36
Results of the competition in Wiesbaden (D) show an average of
1,02 (not taken in account BO's)

This means my results in dynamic should be better (should be
90 m pb).

Knowing that I train hard for dynamic, and as good as never train for static, makes me ask what coud be the matter.
Bad technique?
too little power in the legs?
or is the problem just in the head??

Someone else with the same problem?
