You'll generally see shifts in return rates throughout recruitment, depending on the chapters. You say that there are 5 chapters that are all considered very good. In that scenario, these chapters will likely see very strong return rates in the first 2 rounds, and may see a decline when the PNMs start their selection between those 5 chapters (if they are considered fairly equal).

If a chapter is averaging 90% returns each day of recruitment, that is considered very good.
