00:53:220 (1,1) - too little recovery time for a normal, you need to give players of this skill level time to react to the change from spinner to slider/circle
id suggest using a smaller sv range. it currently goes all the way from 0.7 to 1.4. for a normal this is a big range. if you do reduce it make it a smaller range like 0.8 - 0.9x/1x
