ZAP Attack proxy History Request ID is not consecutive

Question

I've used ZAP to intercept traffic .

Works nicely and I have a history for my REQUEST - RESPONSE pairs like this:

ID      Req. TimeStamp                  Method     etc ..
...
1955    Tue Apr 05 15:42:47 CEST 2016   GET        https ://...
1971    Tue Apr 05 15:42:49 CEST 2016   GET        https ://...
1984    Tue Apr 05 15:43:30 CEST 2016   GET        https ://...
1998    Tue Apr 05 15:43:31 CEST 2016   GET        https ://... 
...

How come the IDs are not consecutive ?
