Converting the small amount of crystal dust into crystal energy allowed Yoze to slightly cut down the amount of time he needed to wait for his crystal nerves to collect enough energy. However, the small amount that was converted simply wasn't enough to make any meaningful difference and he would need the crates full of crystals that he had purchased back in New Swampscott City to make a difference.
While he wanted more than anything to race over there and dive straight into the crates and absorb every last crystal he knew that the amount of enough needed to complete that desire wasn't worth the time traveling over there. He could call Tiki and Dreyer over to ask them to provide him with the crystals that they brought over but that would only give him an extra 40 crystals.
