Transfer answer added by OP to question during period OP could not post own answer:
Here's the code I worked out from the helpful links in my question:
Sub PopCells()
' Define Variables
Dim RowLast As Long 'Last Row with Data in it
Dim CpRange As String 'Holds range of data to select when using a variable
' Find the Last Row with Data in it
RowLast = ActiveSheet.Cells(Rows.Count, "H").End(xlUp).Row
' Clear out old range of data
Let CpRange = "H6:ZZ" & RowLast
ActiveSheet.Range(CpRange).Select
Selection.ClearContents
' Set the current row to the first row with Data
CrRow = 5
' Loop copies the current row, pastes it to the following row
' And increments the time frame by the time increament value
While Cells(CrRow, "H") <= [G2]
' Select the entire current row
Let CpRange = "H" & CrRow & ":" & "ZZ" & CrRow
ActiveSheet.Range(CpRange).Select
'Copy Selected Row
Selection.Copy
' Increment to the Next Row
CrRow = CrRow + 1
' Select the entire current row
Let CpRange = "H" & CrRow & ":" & "ZZ" & CrRow
ActiveSheet.Range(CpRange).Select
' Paste in copied row
ActiveSheet.Paste
' Update time
ActiveSheet.Cells(CrRow, "H") = ActiveSheet.Cells(CrRow - 1, "H") + [$D$3] / 1440
Wend
End Sub
