To be honest, speed is ok. Bounds and strength seem to be ok. It seems like the potential is there. It may simply be a matter of learning how to wait. As you progress in the triple, one of the toughest things to learn is to ride out your phases as long as you can before attacking the ground.
I assume you dont have any video of you jumping, right?
I always enjoyed short approach jumps with just the first two phases into the pit. Bound/run out, not a full landing. It helped me to hold my middle phase longer. Good blocking with the arms will help to reinforce both the holding of the phase and attacking the ground in transition.
Btw..whatever you do. Do NOT lift all the way up until the meet. Since this could be it for you, treat it as a championship event and cut the weights out or down a good 10-14 days prior.
