There is no such "chart" per say, but some manufacturers, within their advertising, have, in the past, identified strong points of their products in a column-type format.
I can tell you this. Bushnell Elite 3200s Nikon Buckmasters (the older models), and the Leupold Vari-X III series, have 88% light transmission. The New Nikon Buckmasters have 92% light transmission. The Elite 4200s and Nikon Monarchs have 95%. The new Leupold VX-III series have more than 95% (I think somewhere between 96% and 98%). The Leupold LPS series (if they still make them) are 99%.
Hope this helps.
