I think you’re mixing up veritical and horizontal.

You dont have to be at your 100% speed, that also does’nt mean you should be at 90% of your speed, but whatever you do dont slow down…
The faster you are at the board the better you will jump.
At the board you have to be able to transform veritcal velocity to horizontal velocity, taking this concept, if your verical velocity is fast, you horizontal velocity will be fast too, to carry your body farther. Thats what the runway in LJ and TJ is for. Use it. This principle is very important for LJ.
For TJ its different, you are trying to maintain your vertical velocity as far as possible through out 3 phases.
