Setting pixel size and position of window

[terrypin]

I'm trying to use this code near the start of a macro to set the size and position of the Excel window in pixels.

Sub TestSizePosition()
'Size/Position Tracksheet
Application.WindowState = xlNormal
Application.Left = 200
Application.Top = 1
Application.Width = 800
Application.Height = 800
'But the results are very different to the values set

End Sub

As you see below, the actual results from a few tests bear little relation to the settings.

---------- SET ---------  -------- ACTUAL ---------
Left,Top  Width x Height  Left,Top  Width x Height
========  =============   ========  ==============
0,0        1000 x 1000     -2,-2     1333 x 1208
2,2        1500 x 1080     1,1       1928 x 1208
1,1        1800 x 1000     0,0       1928 x 1208
1,1        1600 x 1000     0,0       1928 x 1208
1,1        1200 x 1000     0,0       1600 x 1208
1,1         900 x  960      0,0      1200 x 1208
1,1         800 x  500      0,0      1066 x  666
200,1       800 x  800    265,0      1066 x  666

What is going wrong and how can I get an accurate result please?

I've attached an example of the workbooks I want to size.

EDIT: A short time after posting I found a page which implies the actual values are roughly 3/4 of the Settings. So are there no commands for generating exact pixel sizes and positions?
