If the number of objects varied, this would result in either missing objects on some frames, or too many objects on some frames; the latter case could cause crashes. Since it used the current frame to get the count, if the FIFO is started before the FIFO analyzer is opened, then the current frame is effectively random, making it hard to reproduce consistently. This issue has existed since the FIFO analyzer was implemented for Qt.
