Here is the latest Lap Differential chart (updated 3-15-20). This chart shows the Lap Differential as the "average" of the top 2 lap totals for each racing class. The chart has been simplified versus the previous "matrix" type chart.
We have been using this Lap Differential chart for several years now and it has allowed us to race all of our different racing classes together (i.e., "Mixed Race"). The purpose of the Lap Differential is to level the playing field between the various D3 hardbody racing classes, thus enabling us to race whatever class we desire.
Since the Lap Differential is based on the best lap total record for each racing class, the lap differences between classes can be equalized somewhat by assigning a lap differential from the fastest to the slowest racing classes.

The Lap Differential chart has been updated. The latest update includes some new classes (FPS, Porsche, Mid-Engine) as well as an adjustment to the "Best Lap Total" and the adjusted lap differences.
The "Best Lap Total" now reflects the "2nd" best lap total instead of the very best lap total. This change was made to discount any lap total record which is significantly better than the second best lap total. The GTP best lap total was 261, it's now 259 which is second best lap total for this class. This change helps to normalize the best lap totals for each class rather than rely a possible "hare lap total" which is significantly better than the second best lap total.
As far as the "adjusted" lap differences, the chart now reflects the lap differences between classes "and" a multiplying factor of .9 What this means is that whatever the lap difference is between classes, a multiplying factor of .9 is used to determine the final lap difference. For example, if the lap difference between two classes is 10 laps, the adjusted lap difference will be 10 X .9 = 9 laps. This adjustment is similar to the racer handicap system which uses a .9 multiplier to determine the racer handicap (rather than using a 100% factor).
The above changes are designed to provide a more level playing field for all racers. It's not perfect, but we will strive to make it better whenever possible.

The "Lap Differential" chart has been updated (5-1-18, see Post #1) to include the newest racing class: DTM/GTR/GT3/Super GT. The "LD" for this new class was determined by using our recent enduro race results and comparing the results with some past enduros, namely the GTP enduro and 2nd Chance GT enduro. The initial Lap Differential for this new class will be updated when necessary to reflect results from our monthly races.

The Lap Differential chart (matrix) has been revised. This latest version uses a simple layout showing the Lap Differentials for each D3 Hardbody racing class. This latest version changes how the Lap Differential is calculated by averaging the "top 2" lap totals for each class. The chart (matrix) itself has been simplified eliminating the "matrix" which was probably confusing to some. The result is a more simple presentation of the lap differentials. Note: the DTM/GTR/GT3/Super GT lap differential was calculated using the recent enduro results (estimate equivalent to a regular race) along with the first race result (5-20-18). This value will be revised as we have more races. Also, the "Short Track NASCAR" lap differential is a preliminary value based on the 5-20-18 race results but will be revised as soon as more races are completed.

The Lap Differential chart has been updated (see Post #1) to include the new GTP lap differential. Thanks to Eddie Shorer for giving the other classes a lap or two more since he established a new total lap record for the GTP class of 265 laps. The Lap Differential is now 264 for GTP (was 262). Also, the new record affected everyone's Racer Handicap. Most racers now have one or two more handicap than previously. Thanks again Eddie (just kidding Eddie, but new records tend to help the rest of us).
Welcome to Shoutbox. Post your viewpoints here, but keep your posts civil.
Keith Tanaka: The mid-engine Lotus Europa will be allowed to race in the Foreign Production Sports (hardtop) class. The D3 Hardbody rules have been updated to include this revision (see post above).

Keith Tanaka: Just heard the sad news today. Jay Henry passed away. He battled cancer although he didn't want others to know of his health condition in the last year or so. We'll miss his enthusiasm for our hobby. RIP Jay.
