I've come across this site by Gary Breuggman that is 10 years old. I don't know about how reliable it is, but it studies the possibly models of unit, line, and individual replacement, with rather comprehensive illustrations:

There, he concludes that individual rank replacement during battle lulls was probably the most likely method of infantry relief, even in entire unit replacement.
