Can eValid measure response times within a script when those times depend on back-end server delays?

Yes, eValid can do that.

What is required is to identify something that is visible on the screen (the browser face) that shows that the back-end server has finished its work. That usually is a message saying "data recovered" or "computation complete."

Once you identify that, then you write a synchronization command that is based on that text, followed by a ReadTimer command.

In some cases, you need to be able to synchronize on some internal signal that is stored in the DOM. We have one customer who, just for purposes of precise timing, installed a special DOM property name in a particular element on a page that had its value changed after the back-end server completed its work. In that case the timing data was very, very precise (10 msec resolution, with synchronization retries set to 100 Hz).
