Would we be able to detect the gravitational waves if the object masses 
were very different? I mean, as a layman it seems to me that with larger 
mass difference, the smaller mass would have faster orbit if the event 
duration is constant. This again could mean that the frequency of the 
wave to detect would be higher, which could mean it would be out of 
range for our current instruments. If this narrative holds, then the 
observed effect would be explained by our current instrument limitations.
But I am not a gravity physicist. :) What do we currently know about the 
bounds of observation for LIGO et al?
