Sleep function

I am uisng

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

in code to get a Loop to sleep, then restart.

I looking to get the loop to sleep 10 milliseconds, but its costing 150 to use the sleep.

If I set sleep to 0 milli and do a test loop 20 times
St time. 00.00
end time 00.00

If I set sleep to 5milli and do a test loop 20 times
St time. 00.00
end time 00.3125

If I set sleep to 10milli and do a test loop 20 times
St time. 00.00
end time 00.3125

Any thoughts on improving this

Sub SleepVBA()
Dim startTime, finishTime, totalTime
startTime = timer

 i = 0
 Do Until i = 20
    i = i + 1
      
       Sleep 0 '
 Loop

finishTime = timer
totalTime = finishTime - startTime '
Debug.Print totalTime
End Sub
