GM is moving to Available Days Supply (ADP) for Corvette allocations. It does change the whole process but it is the same as most other lines from GM.
I don't understand the differences in the process very well but there is quite a bit of info about it on the forums.
This is how I understand it as described by another member. Thanks John from MCF
AVAILABLE DAYS’ SUPPLY (ADS) CALCULATION METHOD
• When does GM use the ADS method? GM uses the ADS method the majority of the time.
• How does it work? GM allocates vehicles to the dealers with the lowest Available Days’ Supply (ADS). A dealer’s ADS is based on the dealer’s Total Availability and Daily Sales Rate for the allocation group.
• What is a dealer’s Total Availability? A dealer’s Total Availability is the quantity of vehicles of the specified allocation group that a dealer has available. This quantity is equal to the total number of vehicles in stock (on ground), in transit to your dealership, in system (orders that are being built), placed orders (orders that are ready to go to the production management system), and balance-to-go allocation (the dealer’s final allocation units that have NOT been submitted as preliminary orders or selected as placed orders for the current production period).
• What is a dealer’s Daily Sales Rate? A dealer’s Daily Sales Rate is the average number of units sold per day over a sales period of 1, 2, 3, or 12 months. GM determines which sales period to use for each allocation group. (GM uses 12 months only during the start-up and build-out periods for an allocation group.)
• What is a dealer’s ADS? A dealer’s ADS is equal to the dealer’s Total Availability divided by the dealer’s Daily Sales Rate. (For example, if a dealer’s Total Availability is 30 and its Daily Sales Rate is 2, then its ADS is 15.)
