Inaccurate query results of HKStatisticsCollectionQuery

I have the same issues, when i use HKStatisticsCollectionQuery query user step count, there's a big difference in the number of steps I'm query before and after a minute's interval. 2023-12-17 15:45:41 steps=529 2023-12-17 15:46:52 steps=5817

2023-12-19 19:43:59 steps=2680 2023-12-19 19:44:31 steps=5554

What is causing this issue? I would like some assistance, please.
