What/why are you adding for your conversion from mag to true?
The correct way to read a VOR from a chart is with a chart plotter lined up to the magnetic flute on the top of the VOR rose. When I measure the examples you are giving I get with a degree (subject to my eyesight) of the published radials.
So I suspect you are not measuring correctly or have a misunderstanding of how to plot a VOR radial on a chart. You do not measure true and then add variation you measure mag and you plot mag. Thats what the flute on the VOR rose is for.
