Ryzen balanced power plan advice

Default minimum CPU state in Ryzen balanced power plan is 90%. In that state in Ryzen master all my cores are at 3.4ghz (r5 1600). When I put minimum cpu state to 5% they fall, some cores to 1550, some to 1511mhz. Is it better to keep that at 5% or at 90%? At 90% CPU is always on max?
