but my step is my longest I think
Although this may be true, I find it highly unlikely. If possible have a friend or coach measure your phases to give us some parameters in which to determine if the hop phase is really a problem. Forgive me for my ignorance but I need to respond in feet and inches. Your jumping approx. 12.50 m(41ft). You think your Hop,step phases equal 8m(26ft). This means your jump phase is approx. 14ft . All this running of the mouth is just trying to point out how short your jump phase is if in fact it is your shortest.
My guess is there are some posture problems in your technique that need to be corrected in order gain distance in your jump phase.
