[ndnSIM] PIT size

Hi all,
I have a basic question about PIT size and its role to control the traffic flow.

In my scenario when I change the PIT size into the lower value,  the result shows more DropData.
I reckon the small size of PIT means the small number of data requests and consequently the small number of DropData but large number of InterestData. Is It so?
On the other hand, when PIT overflows, we would expect an increase rate of retransmissons from the downstream nodes. What would be the role of increasing retransmission rate on the packet drops both on layer 2 and 3.

I really appreciate your response in advance!
