Gearbox "backlash"

Somebody asked a question about how much slop one could expect in a gearbox. I checked my 9" A and in the A range (fastest feed coarsest thread) is see only a little, maybe 5 degrees or less. On the "E" range (slowest feed finest thread) I see about a half turn on the input shaft between feeding forward and feeding reverse.
