F1 All Time Stats as of April 2023

 After 24 seasons the ISF (International Sportscar Federation), has built up quite a few stats.

Here is a list of the leaders all time in F1 division.

LMP All-Time Stats Updated March 2023

 

 
The Mega G chassis and bodies were released in the early 2000's. ISF brought LMP back. Most of the field were in Peugot style bodies with Ev Kamikawa being the only consistent
Audi style body runner

The ISF has ran the LMP division under three different guises. The first was a separate division using the Tyco wide pan chassis and open top sportscar bodies. Drivers decided that concentrating on the GT and GTP divisions would be better for competition and for cost control. The ISF then decided to allow the Tyco LMP bodies and chassis into the GTP division to allow some more variety in the GTP body styles. Since GTP ran the AFX Super G+ chassis and bodies, the ISF decided that anyone running the Tyco chassis and body could use silver springs and motor brushes, ski style pick up shoes, and non slip Wizzard tyres to equal the performance advantage the Super G+ chassis cars. While many drivers tried the car in this configuration, only Mike Fitzlaff and Mark Walczak made multiple starts in it. Walczak being the most successful picking up one win with that combination. LMP disappeared for several seasons while ISF concentrated on just the GTP and F1 divisions. When Mega G chassis and bodies came out they were immediately popular for their looks and speed. Several exhibition races were held with the cars over several race tracks. The car performed well in those races and the decision was made to adopt the car as the new LMP car. After the first few races it became apparent that the chassis was not holding up to the rigors of the ISF tracks and schedules with several incidents of divers leading races only to have the car fail on them became too numerous for the drivers to stand. The Mega G cars were shelved after a couple of seasons. They were going to be brought back for a race during the 20th ISF anniversary season as a special event, however driver protests and a near boycott of the event they were going to brought back for sealed the fate of the Mega G car and there hasn't been an LMP race since 2019. 
Points were originally awarded down to 8th place for the first few seasons 

(10 for the winner, 8, 6, 5, 4, 3, 2, 1)
then the points were awarded to 10th place for the last few seasons

(15 for the winner, 12, 10, 8, 6, 5, 4, 3, 2, 1)

ISF LMP Division ALL TIME Stats
as of March 2023

 

Peugot and Audi were the two dominant Mega G bodies at the time the ISF ran these cars in the LMP division. While good looking they didn't always handle the scenery well around the ISF race tracks at the time. They often got stuck under guard rails. The longer bodies also called for a change of the corner aprons as the cars would start to drift and hit the wall too fast under normal racing conditions, or slide too far over the track curbing and prematurely dropping the wheels off the track and causing spins and de-slots.

All Racing...........       G-B Main and A Main (Final Race)

Mains will be the Alphabet style ladder. 

Road Course:

All mains B and lower are two 2 minute halves

A main is 4 minute halves 

Ovals:

All mains B and lower are four 1 minute quarters

A main is four 2 minute quarters - (run all lanes)

A Main = Polesitter + top 3 from B

B Main = 2^nd fastest qualifier + top 3 from C

De-slots and DNF:

A Main......................... All divisions unless otherwise specified 12th off is a DNF

H-B Mains.................. All divisions unless otherwise specified 8th off  is a DNF

There are no longer time penalties for 4th, 8th, or 12th de-slots

• Crashing "off the table" at any point during a "Main" event (C, B, or A) is also a DNF

“Off the table” is defined as off the surface the track and hitting the floor

Cars landing on controller holders, drivers, or marshals does not count as a DNF

Points........................... All divisions

                                        -Order of finish points are as follows: 15, 12, 10, 8, 6, 5, 4, 3, 2, 1 through top ten

                                        -Main race victors receive 1 point

                                        -Pole winner does not earn a point as the reward is making the final

 

Order of Finish           All Divisions

• A Main winner                      = 1st
• A Main 2^nd place                   = 2nd
• A Main 3^rd place                   = 3rd
• A Main 4^th place                   = 4th
• B Main 4^th place                   = 5^th
• Highest remaining finishers in C, D, E, F, G, H mains fill remainder of points finishes

• If pole sitter pulls out of A Main, the 4^th place finisher from the B Main advances.
• The pole sitter then gets 5^th place in the event final standings
• If a driver crashes out of an event, remaining drivers must pass their lap total to advance
• A driver who suffers a DNF but has lap total higher than remaining running cars still advances
• Running order shown on computer is final decision maker for race order

 

Dropping Points         All divisions

-A drivers single lowest points finish in every division is automatically dropped after last event

-A DNP counts as zero points and will count as the dropped event

--------------------------------------------------------------------------------------------------------------------------------

Children Racers

Children, under the age of 16, but at least 10, who are directly related to an ISF member (i.e. son, daughter, nephew, etc.) may race in the GTP, F1, GT & LMP categories if they can meet the following criteria:

                                        1 -- their best qualifying lap is within 120% of the polesitter's time

                                                for example, if pole speed is 6.545 seconds, a time within 120%

                                                must be under 7.854 seconds

                                        2 -- they had no more than two offs during their qualifying run

                                    3 – they can run at least two minutes at speed with three offs or less

These rules have been set to be sure that young racers can show two things: good car control and good pace

The ISF founders felt that 120% would be a reasonable mark for pace, and more than two offs in 12 laps would be a bit too much

Rules apply to children racers until they prove that they can meet these criteria on a consistent basis.

--------------------------------------------------------------------------------------------------------------------------------

Car Brand and Special Modifications

-Different brands of cars may be allowed modifications to help equalize the field at discretion of ISF commissioner and test results

-Modifications can’t be run the night of the suggestion or event, except in a practice test after the current event for future consideration

• Race host DOES NOT have to serve food, however drinks are appreciated. Inform drivers if there is no meal available
• Drivers are asked to give a free will donation of whatever dollar amount to race host for meal or drinks

--------------------------------------------------------------------------------------------------------------------------------

• Drivers can choose any manufactured car/sponsor to race. F1 must represent a real F1 team from 1951 onward
• Drivers can create their own F1 team with approval of ISF board, must be F1 related (i.e. Super Aguri = Super Kamikawa)
• Once a car/sponsor is taken, no other driver can race that car/sponsor without permission of original driver (exception is a new driver, who shows up or is given, a temporary car to race)
• Drivers can race cars from the same team provided that the sponsors are different (i.e. Winfield-Williams and Rothmans-Williams), and the cars look significantly different (team of red chaparral Ferraris can’t compete with red F1 Ferraris because of similar colors)
