I believe there is more of a gap from bare bow to compound, than there is from compound to crossbow ...... in other words, the modern compound is more related to the crossbow than to a recurve or longbow shot instinctively and with fingers ....... but that's just me ...
And as well I could say there is more of a gap between compounds and crossbows than there is between a firearm and a crossbow...........I'm just sayin.
