In many applications, there may be a limit on the number of customers that can wait before being served, which is called the buffer capacity. When the buffer is full, any new arrivals are turned away, which is called blocking. As the buffer capacity is increased, the proportion of blocked customers $\_\_\_\_\_\_\_,$ and more customers are able to get into the process. At the same time, the average waiting time of the customers who do get in $\_\_\_\_\_\_\_.$
