Buenas me gustaria que el interval de mi autoclick fuera picosegundo mi codigo es este:

Public Class Form1
    Private Declare Sub mouse_event Lib "user32" (ByVal dwflags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cbuttons As Long, ByVal dwExtraInfo As Long)
    Private Const mouseclickup = 4
    Private Const mouseclickdown = 2
    Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
 
 
'En el Timer1 ponemos:
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Windows.Forms.Cursor.Position = New Point(Windows.Forms.Cursor.Position.X, Windows.Forms.Cursor.Position.Y)
        Timer1.Interval = NumericUpDown1.Value
        Label1.Text = Windows.Forms.Cursor.Position.X
        Label2.Text = Windows.Forms.Cursor.Position.Y
 
        Windows.Forms.Cursor.Position = New Point(TextBox1.Text, TextBox2.Text)
 
        mouse_event(mouseclickdown, 0, 0, 0, 0)
        mouse_event(mouseclickup, 0, 0, 0, 0)
 
        Windows.Forms.Cursor.Position = New Point(Label1.Text, Label2.Text)
    End Sub
 
 
'En el Timer2 ponemos:
 
 Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
        Dim hotkey As Boolean
        hotkey = GetAsyncKeyState(Keys.F9)
        If hotkey = True Then timer1.start()
        Dim hotkey1 As Boolean
        hotkey1 = GetAsyncKeyState(Keys.F10)
        If hotkey1 = True Then Timer1.Stop()
    End Sub
 
 
'En el Timer3 ponemos:
 
    Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
 Dim Posicion As Boolean
        Posicion = GetAsyncKeyState(Keys.F7) 
        If Posicion = True Then
            TextBox1.Text = MousePosition.X : TextBox2.Text = MousePosition.Y
        End If
        If Posicion = False Then
        End if
    End Sub
End Class
