As if this was not complicated enough following this site speed is effected by other variables as well

heres a some charts that show speed difference just with weapons racks is - 10 to -13mph, while difference in fuel grade can drop speed by additional 10mph or so.

a MUSTANG in clean configuration at a specific altitude can manage 410 mph , but if you sling ordnance under it the speed drops any were from 35mph to 54mph when the total mass increases by merely 1000lb.
near as I can figure it the mass increase alone should only result in a 20 mph drop in top speed, so the rest must be increased drag. I can imaging several HS-293 slung under the belly of a HE-177 must really slow the beast down
