Wonder if can believe the test

I must admit that I was really surprised today when I made my chart comparing the Oly 40-150 to the Oly 45mm.  I am not sure I can believe the slrgear.com test results.  The cheap 40-150 has some bright pink areas at 40mm and F5.6 to F8 whereas the highly thought of $350 45mm does not.  It appears the 45mm has a uniform sharpness edge to edge but the 40-150mm has an average sharpness that is higher because the squares of bright pink are greater in number than the darker pink squares.  I wish I could get my hands on the lens and test it myself.

One great use for me of the 45mm would be I enjoy photographing paintings in art museums.  But for now if the resolution charts can be believed I see no advantages for the 45mm to photograph landscapes at F5.6 to F8.
