Previously, when you dropped an ally you would be refunded 60% of the price when you purchased the ally (which is 57% of the price that you see when you are the owner). The refund amount is now based on the number of days you have owned the ally. The amounts in the list below represent the refund you would received expressed as a percent of the hire price with you as the owner. Percent refunded by days of ownership 2.5% 5.2% 7.9% 10.8% 13.8% 16.9% 20.2% 23.6% 27.2% 30.9% 34.8% 38.9% 43.1% 47.6% 52.2% 57.0% A note for math geeks - the difference in refund received is driven by an exponential formula.
