While working to complete the "Giulietta Jam" series I noticed that the competition in the Tier 16 Daytona Road event was particularly tough. Over several days I often finished 4th or worse. Kept at it and finally finished 1st but not by improving my time. Here's how the sequence played out:
(1) My 5:37 was 7 seconds behind the guy in 1st place. Situation looked hopeless.
(2) Almost a second slower but now I'm only 5 seconds behind the leader.
(3) Even slower but now I'm less than 2 sec behind the leader!
(4) Worst time of all but all the faster drivers retired and I won by 5 seconds!
This pattern has been consistent thru my entire time with RR3. The "bots" don't get slower; they retire from the event leaving you in first with the same or worse time than you started with. An odd way to design a game that supposed to give you tough competition.
