P1TS Fact Sheet    March 3, 2020 http://p1ts.com/docs/factsheet.html

P1TS is software that helps race engineers and strategists make informed race decisions by improving situational awareness from Timing and Scoring data that competitors license from IMSA.

This Fact Sheet briefly illustrates how P1TS can be used to assist race engineers and strategists in solving many of the race strategy problems they face by understanding data such as: lap times, gap times, driving times, pit times, and their deltas and trends. For a thorough review description of P1TS, please refer to the following guides.


P1TS has fairly modest hardware and software requirements.


The Leaderboard table displays key data about each competitor.
  • You may reduce noise by selecting the classes and columns you wish to Show/Hide.
  • Your Hero car (#56), Sister cars (#65, #43 on page 2), and other cars you want to closely Follow (#17, #28, #73, #81, #44, #31) are highlighted.

Track Map

The Track Map individually models car movement using their earlier sector times.
  • Hero (#56) and Sister cars (#65, #43) can be immediately located by Target Boxes and Radar Lines.
  • Follow cars (#17, #28, #73, #81, #44, #31) are larger and have Data Boards circulating with their car markers, showing their Class Position as well as their start/finish Gaps and Closing Rates relative to your Hero.
  • Non-follow cars are smaller reducing noise.
  • A Hero Tail configured with your pit delta allows you to see how a stop affects pit stop overtaking.
  • Target Boxes also highlight class leaders.
  • A Circular map (not shown) may be used to easily visualize the circuit by time.

Track Order

The Track Order panel accompanies track map to help visualize IMSA Full Course Yellow Pass-Arounds behind SC or overall leader. Ordering is updated at every intermediate timing loop crossing.

  • C: Pass-around eligible cars between SC and class leaders will be vertically offset.
  • CP: Class-color coded class scored position (updated at S/F).
  • Lap: Number of completed laps.
  • L Stnt: Number of laps in current stint.

Cars 11 and 3 are eligible for pass-arounds.

The Sectors panel details sector and lap times for the selected car.

  • The Working lap's (L62) sectors times are recorded as sectors are completed.
  • Faster and Slower arrows show how each working lap's sectors compares with his Best, Rolling, and Theoretical lap's sector times.
  • E-prefixed (estimated) lap times (circled), predict the working lap time, by pulling remaining sector times from Best, Rolling, and Theoretical.

Pits & Stints

The Pit In-Out Stints panel displays both the session chronology and summary of driver and pit lanes times for the selected car. The pit-in and pit-out time line crossings divide the chronology.

IMPORTANT: The straightforward time division employed here does NOT capture the changing intricacies of IMSA's drive time calculations. Also, while delayed driver plug ins during driver changes may be manually corrected by IMSA, P1TS can only rely on information available in the timing stream. You should have an additional means of calculating drive times.

Race Gap Chart

The Race Gapchart assists strategically visualizing the race via a chronological view of time gaps to the Hero car. The X axis tracks the most recent (50) laps and the Y axis displays +/- time gaps.

  • Cars ahead of the hero are above his Y=0 line while cars behind appear below.
  • Pit stops are indicated as circles.
  • Yellow flag periods are displayed as vertical bands.
  • A dotted horizontal (orange) pit stop delta line allows you to visualize overtaking in the pits.
