Mach difference at equal cost index comparison

Hi all,

I'm interested in comparing the mach numbers your FMS's calculate for a given cost index. Can some Boeing and Bus (+other) drivers please post what their typical figures at a given cost index and altitude are?

If you need a reference, try a cost index of 35 at FL350 (assuming ISA).

Thanks!
